In low-lying areas building anti-floating design is not accurate,fortification level unreasonable problem,put a new kind of low-lying areas building anti-floating design and fortification level determination method were forward. Based on the analysis of engineering in the low-lying areas of the distribution of the underground water level and have to withstand buoyancy value basis,in a building project,for example has carried on the detailed analysis,project engineering general situation is given. The locati...
