With the requirements on the full use of architectural space and the high-rise buildings built, most of the buildings have basement which is not only one layer, leading to the bottom of the basement level is far lower than the perennial ground water level, especially in the coastal areas or areas along the river, obviously groundwater play a important role in structure.
Phenomenon of up-loating accident After the accident, the damage detection of structures was detected by professional and technical personnel.
(1)Partial non-construction of anti-floating anchor rods The non-construction works of section C,such as non-beam –slab of patio of the first floor underground , anti-floating anchor rods lying in the bottom of the sight-seeing lift and the construction area of tower crane close to patio, could be deemed as the starting point of upwards-floating , especially when the water level rises ,which could give rise to the partial floating

They have received much attention because of their outstanding physical properties including low water absorption and low outgassing.
The cured specimens were removed from the mold and cut with a water coolant to required sizes: 15 mm×10 mm×4 mm (type I) and 27mm×27mm×4mm (type II).

Introduction Clay is an important material found in several types of rocks, water resources, and even in atmospheric aerosols [1].
In addition, the pH of a bentonite-water dispersion was also determined by placing 25g of bentonite sample in a neutral solution of deionized water.
The pH of the bentonite-water dispersion was measured after 2h standing time using a pH meter.
Finally, the pH of the bentonite-water dispersion is 7.1.

Water was recirculated, keeping aeration constant and water temperature at 20.0±1.0°C.
About 50% waters were replaced every other day.
Weighed accurately 1000 mg norfloxacin in a 100-mL volumetric flask, and added a little 5% acetic acid to dissolved, then 10 g eel feed was added and the mixture was diluted with water to volume.
Ltd., Switzerland) and reconstituted in 2 mL of 1M potassium dihydrogen phosphate (pH 7.0)-methanol, and 2 mL hexane solution saturated by water was added.
Pharmacokinetic analysis Pharmacokinetic non-compartmental modeling of the drug concentration-time data was performed using DAS Version 2.0 (Drug and Statistics Software, which was developed by Mathematical Pharmacology Professional Committee of China, which is authorized and supported by State Drug Administration of China).

Water, as a precious resource, is an essential element for the ideal living places.
To take advantage of people's special feelings for water, waterscape villas have met the aspirations of the people to live close to the water.
Villas usually have one side or two sides facing water, the more surrounded areas are, the higher added value of the villa is[1].
The villas on the island surrounded by water are ultimate representation of waterscape villas.
The foreign representative villas which are commissioned by professional designers are not replicable, such as Falling water house, The Villa Savoy, and Farnsworth House.

The annual maximum frozen soil depth of 56 cm. (3) The water situation: Shijiazhuang City, multi-year average runoff depth of 90.1 mm, the annual runoff of 2.99 billion meters.
But through the analysis of soil temperature, soil, water and solar radiation and sunshine, Shijiazhuang has rich shallow geothermal energy resources available.
Can temperature the temperature, the heat pump unit is reliable, stable, can ensure the efficiency and economy system. [2]According to the relevant statistics, the heating energy consumption in northern heating areas of our country building total energy consumption accounted for 65%, up to 90% in some areas, mainly used for heating, air conditioning and hot water supply.
The comparability of two heating methods 4.2 The working principle of ground source heat pump Use of geothermal resources construction can be from two aspects: the geothermal heating and geothermal hot water supply.
The main problems are the following points [7]: Shallow geothermal energy resources is not clear, basic work is weak.Relevant laws and regulations, standards, system is not perfect.The social awareness of shallow geothermal resources utilization deficiency.Market access system is not perfect, professional technology level uneven. 8 Summary The use of shallow ground source heat pump technology to replace the traditional heating of buildings (cold) energy of choice, it is worth to popularize.

Although there are standard methods such as AATCC195-2009 [9] and maturely applied instrument MMT [10], which can be employed to measure the fabric moisture management properties including water absorbency, water repellency and overall moisture management properties, the measurement system reported in this paper focuses on the characterizing method of liquid moisture transfer difference between two surfaces of textile fabrics, which is the most important parameter to reflect the dynamic liquid moisture transfer properties and comfort sensations of textile materials.
There is a fine water pipe fixed through the central sensor of the upper measuring head, which can supply a predefined amount of test solution (synthetic sweat) with the water storage box and control system during testing.
By testing the resistance changes between the measuring rings of sensors, which will reduce when the fabric is wet or contains a quantity of moisture, the changes of water and liquid moisture content on the fabric upper and lower surfaces (UU and UL) can be measured.

With the rapid economic growth of lake basin, people chased the abundance of material life crazily, and large quantity of “three wastes” (waste gas, waste water and waste residues) were discharged into the air, water and soil, etc, which posed a great threat to the heath of lake basin.
According to the test results from professional testing laboratory, the content of several common heavy metals in the sediment core were much higher than background value.

Nevertheless the negative friction of sandy foundation is insufficient to balance against the lift, thus gravity-based foundation and tremendous concrete construction must be constructed, which increases the workload and construction difficulty. 3) High cost of corrosion protection As the coral reefs of South China Sea is typical high temperature, high humidity, high salt fog area, the critical factor for maintenance of facilities is against water and salt corrosion.
Compared with the high cost of power storage, storage of water and cool is technically available and sufficiently economical.
It is difficulty to provide long-term professional maintenance stuff.
