Method and device for determining joint leakage of foundation pit bottom-falling type waterproof curtain
The invention discloses a method and device for determining joint leakage of a foundation pit bottom-falling type waterproof curtain, and the method comprises the steps: obtaining a plane position of the joint leakage of the foundation pit bottom-falling type waterproof curtain and a three-dimensional fluid-solid coupling numerical calculation model; on the basis of the plane position of the leakage at the joint, setting different leakage parameters at the joint; the different joint leakage parameters are combined with the three-dimensional fluid-solid coupling numerical calculation model for calculation, and the quantitative relation between the leakage parameters and the underground water level outside the pit and the quantitative relation between the leakage parameters and ground subsidence are established; and according to the quantitative relation, the specific position and range of leakage at the joint of the foundation pit bottom falling type waterproof curtain are determined. The method is suitable for engineering construction in which leakage risks exist in a water-rich stratum bottom-falling type waterproof curtain and leakage point identification needs to be carried out on a leakage risk area; and meanwhile, the method is also suitable for identifying leakage of other types of waterproof curtains at the positions where the waterproof curtains penetrate through the multiple aquifers.
本发明公开了一种确定基坑落底式止水帷幕接缝渗漏的方法及装置，所述方法包括，获取基坑落底式止水帷幕接缝处渗漏的平面位置和三维流固耦合数值计算模型；基于所述接缝处渗漏的平面位置，设置不同的接缝处渗漏参数；将所述不同的接缝处渗漏参数结合所述三维流固耦合数值计算模型进行计算，建立渗漏参数与坑外地下水位和地面沉降之间的定量关系；根据所述定量关系，确定基坑落底式止水帷幕接缝处渗漏的具体位置和范围。本发明适用于富水地层落底式止水帷幕存在渗漏风险，且需对渗漏风险区进行渗漏点识别的工程施工；同时对止水帷幕穿透多层含水层处其他类型的止水帷幕渗漏的识别同样适用。
