Analysis Of Environment Influence On Water-discharging Pressure Relief For Underground Structure Anti-floating

With the acceleration of urbanization, the pressure of the global population, resources andenvironment increases day by day. The developed countries solve the urban problem and urbanproblem, realize the sustainable development with underground space development and utilization.However, underground structure will withstand a certain degree of buoyancy. In order to slove thisproblem, the engineers usually adopt the method of increasing the self-weight or using the anchorwithout reduceing the water pressure.In order to analysize the environment influence on water-discharging pressuer relief forunderground structure, this paper have the research content as follows:1. First, this paper introduce the basic ideas of dewatering, and put forward the problems to besettled;2. The dewatering should in combination with the diaphragm wall, and this paper present amethod which are in consonance with the finite element calculation to calculate the wateroutput of dewatering under different geological conditions.3. This paper shows the method to calculate the drawdown on the basis of large-well method,then introduces the computing method of ground settlement.4. By using the method mentioned previously, this paper analysize the environment influenceon water-discharging pressure relief for underground structure anti-floating. At last, thispaper put forward the measures to reduce the environmental problems.
