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。
The use of deep foundation pit dewatering near the embankment will have an impact on the embankment due to the large impact of precipitation, causing the water level inside the embankment to change. If the water level falls too much, the embankment may undergo excessive settlement, Dams are dangerous. Adopting ADI-NA software to conduct deep foundation pit dewatering on one embankment and carrying out numerical analysis under different operating conditions, it is considered that when deep foundation pit dewatering occurs after the embankment, the water level in the embankment will decrease greatly, such as recharge, Set up diaphragm walls and other measures to ensure the safety of dams.
