The manual monitoring requires professionals carrying testing equipment to the monitoring site, it is hard to detect the small relative deformation and cannot accomplish continuous acquisition.
Landslides normally occur when the strain accumulated due to percolating rain water develops hydrostatic pressure beyond the elastic limit of the rock.

Introduction
With the aim at reducing the problems associated with water penetration, cavity walls were developed in the UK in the 19th century.
Water that would seep inside the outer (external) wall would then run down that wall, while the inside wall would remain dry.
It was found that these blocks could support a heavy load such as a roof or floor, help reduce problems with water penetration and building insulation.
This problem has not been properly addressed in the past and it becomes challenging for researchers and professionals to gain insight of the structural response of new in-plane loaded masonry walls.

We divided the man-earth system into four subsystem: land use, water resource, environmental and socio-economic system.
Integrated resources carrying capacity is influenced by material, information and energy exchange between land use, water resource,environmental and socio-economic system.
Therefore, this study takes the concept of “land - Population - social - economic - ecological environment” into account, establishes asystem dynamics simulation model of comprehensive resources carrying capacity of Hubei, appraises and predicts the maximum population cap of 17 cities between 2010 and 2020, running on Professional software Vensim_PLE.
As a base for comprehensive regionalization of land use, resources carrying capacity refers to land resource, water resource, environment, economy.
Water resource carrying capacity surpasses other carrying capacity in Hubei except the north central area which has less rainfall and more manufacture.

Effect Evaluation on CFG Pile Consolided Foundation of the Red Clay Being Polluted by Organic Matter
Online since: May 2011
Authors: Chun Mei Mu, Bao Chen Liu, Zhi Kui Liu
Introduction
CFG (Cement fly-ash gravel pile) pile is a certain bond strength of rigid pile which is mixed with gravel pile on the basis of amount of stone chips, fly ash and water mixing a small amount of cement.The aggregate is still gravel, with stone chips to improve the particle size distribution, fly ash to improve the workability of the mixture and amount of cement to decrease its activity, mixed with a certain small amount of cement to bond strength.
Carbonate of limestone distributed in Guilin is formed after laterization to high plastic clay with reddish brown, yellow brown, of which the pore is relatively large, and the high water content.
Compressive strength test specimen In the CFG pile construction site, the standard test block (150 × 150 × 150) is13 blocks in total made by the professionals of the pile after mixing random sample mixture.
The reason is that organic particles are adsorbed on the surface of cement particles and clay particles and hinder and delay the formation of hydration products of cement and cement hydrates and the role of clay particles, resulting in soil and water slurry can not pile the envelope.

Performance Evaluation of Scintillation Fiber-Optic Dosimeter for Measuring High-Energy Photon Beams

Introduction
In general, the percentage depth dose (PDD) by high-energy photon beam is measured with a conventional ionization chamber or EBT films being put in or on the solid water as increasing the thickness of a solid water phantom, respectively.
Fig. 1 shows the experimental setup for measuring PDDs using a FOD when a solid water phantom is irradiated by high energy photon beams.
In the case of the experiment with EBT dosimetry films, the exposed films are scanned by a professional flat-bed color scanner (Perfection V700 photo, Epson), and they are all scanned with the same scan bed orientation.
It shows maximum doses at about 3.0 cm depth of a solid water phantom with three kinds of dosimeters.
Generally, the absorbed doses in a water phantom increase as increasing the field size and as decreasing the energy of irradiated photon beam.
