Introduction Mine gases are dangerous not only for professionals working in underground mines but they can also endanger the lives and health of people on the surface, for example due to the explosion of coal dust, methane, etc.
· Relative permeability is the ratio of the effective permeability for a certain fluid (oil, water, gas) to the overall permeability of the rock [4].

The design elevation of the bottom of the 274# pile cap for continuous girder over the Huaihe River Entrance to Ocean is -7.015m and the measured water level on the field is 1.79m.
Calculation with considering the path effect With each construction procedure implementing in actual construction, the water level of the foundation pit decrease continuously with corresponding peripheral earth pressure imposing on the steel sheet pile.
For example, the purlin whose height is -7.8m can be installed by welding and play a role when the water level decreases to the -7.8m, while steel sheet pile has caused deformation.
Based on the reasons above, the improvement of scheme and constructions lies in reducing the accumulation of deformation to put an forward to improvement suggestions as follows: 1) The construction process changes from pouring the bottom concrete by silting suction to the bottom of the foundation pit firstly to silting suction and installing purlins carried out simultaneously because the bulk density of the mixture of water and mud is greater than the density of water , so we can decrease the internal and external pressure difference of the foundation pit and the load that cofferdam bears. 2) When constructing purlins of the second and the third layer, we should install two 20t-hydraulic jack in inner support of the middle crossbeam and pressure to reduce the accumulation of deformation so that the deformation and the maximum stress are reduced at the same time. 3) We should break the traverse brace piles of the second and the third layer in the middle and connect them with elastic
But the welding and installation of hydraulic jack on the inner support need professional technology and increase the difficulty of installation of inner support, while we can adopt this scheme because the tonnage of hydraulic jack is small and the quantity are few, which can provide reference for other construction schemes.

In china, in the famous national park of Huanglong, Jiuzhai Gou and Huashan there also developed a lot of debris flows and water rock flow [3] .Those debris flows ruin the wonderful landscape of tour resort and threaten the safety of the tourists, and affect the tourism economy.
Tianchi Lake extends in north-northeast direction with an area of about 2.44km2, the elevation is 1910m above sea level, and the total water reserves are 2×108m3 with the largest depth of 103m.
The practical non viscous debris flow calculation formulate in china [6] are used to calculate as below: (1) (2) =debris flow average velocity (m/s); = the roughness coefficient of the bed; =the bed slope; =debris flow depth (m); = the concentration of debris flow , = the concentration of water ; = the concentration of debris flow solid materials.
The concentration of the water is usually 1, and the slope grading is 0.061.

professional wind load calculation method.
The incident potential is: （2） Where is acceleration of gravity; is amplitude of wave; is wave number; is water depth; is wave direction.
（3） This paper adopted heave plate of Spar platform in deep water in order to increase added mass and damping.
Then large size water-entrapment plate is designed to reduce heave motion of wind power system.

Responsible for daily work, monitoring center conducts professional analysis, proposes safe evaluations, timely finds the hidden troubles and kinds of non-standard construction behaviors on construction site, and then submits them to management division for its decision making.
Expert group provides professional advices for management division to handle risky situations and accidents in case of big dangers and major engineering accidents.
After taking vacuum wells to lower water on Sep. 25, the inclination deformation gradually stopped (no excavation conducted).

Similarly, for all simulation, physical properties of the droplet liquid (water) were: initial temperature (285K), density (998.2kg/m³), vaporization temperature (273K), thermal conductivity (0.6W/mK), with the gravitational constant of 9.8m/s².

The tunnel buried depth rangefrom 30mto 72m,tunnel surrounding rock is almost fullto strong weathering basalt, structure ofrock mass mainly as the gravel structure, full of weak interlayer; Groundwater types are mainly of bedrock fissure water, surrounding rock integrity is poor, weak self-stabilityof surrounding rock, tunnel is prone to collapse.
Application of ABAQUS in tunnel engineeringhas incomparable advantages,but still has certain defects;Forinstances, in one hand, if the parts of grid coupling condition is bad, the calculation maybe can’t finish; On the other hand, whena tunnel model is too complex to set up, the other good pre-processing software is needed.In general, under the joint efforts of the professionals, application on ABABUS in tunnel engineering has a very bright future.

As the Lanyan double-line, Yanda ferry, and Delongyan local railways is built, the passengers’ capacity of Yan Tai station will increase substantially, translocation among railway, water transport and road traffic will also further increase[2].

Water absorption test Fig. 6 Water absorption behavior of composites Water absorption test were performed according to ASTM D570 standard.
This test covers the method of determination of water absorption of composites.
These composites were immersed in sea water and river water for a period of 30 days.
The moisture absorption in these composites was measured by the weight gain of the material in regular intervals and depicted in fig. 6 The result of water absorption behavior in sea water of composite-1 is less as compared to the river water.
