Experimental Research on Groundwater Seepage Characteristics of Shore Foundation Excavation in Tidal Reach
The deep foundation excavation project in the cable tower foundation,because it is built near large rivers,foundation excavation dewatering is an important link to ensure the safety of the project.Taking the foundation excavation project of large bridge cable tower close to the tidal reach as the object,the trial pumping test is carried out after the foundation dewatering point and retaining pile construction are completed.Through the monitoring of the water extraction of the dewatering well and the water level changing of the observation well,it is found that due to the on-site support construction and the seepage supply around the locking steel pipe pile,the water level fluctuation of the observation well is not obvious,which has caused great interference to the analysis and processing of the experimental data.The numerical simulation is carried out,the inference that the area is jointly affected by tidal current and groundwater recharge is verified.
