【摘要】 在靠近堤坝处采用深基坑降水,由于降水的影响范围较大,将会对堤坝产生影响,使堤坝内部的水位发生变化,如果水位降幅过大则堤坝会发生过大的沉降,从而可能使堤坝发生危险。采用ADI-NA软件对某一江堤边的深基坑降水,在不同工况下进行数值分析,认为在堤坝后进行深基坑降水时,堤坝内水位降幅较大,需要采取诸如回灌、设置地下连续墙等措施来确保堤坝的安全。更多还原

【Abstract】 Dewatering with the deep foundation pit near a dam has a large area of influence and could change the seepage line of the dam.If the falling range of water level is too large,the settlement could be oversize and the dam could be at risk.ADINA software is used to simulate dewatering in a deep foundation pit at several different working conditions.And corresponding results show that the deep foundation pit dewatering behind the dam could vastly debase the water level and must take measures such as recharging,setting up underground continous walls and so on for the sake of the dam safety.更多还原
