Construction method for silty-fine sand layer seepage interception wall based on river-facing three-dimensional seepage modeling
The invention provides a construction method of a silty-fine sand layer seepage interception wall based on river-facing three-dimensional seepage modeling, which comprises the following steps: S1, arranging a precipitation well in a foundation pit construction area, and measuring the underground water level height; s2, dewatering the interior of the foundation pit through the dewatering well, and measuring the permeability of the aquifer in the foundation pit area; s3, carrying out typical section leakage analysis; s4, the influence of different water head pressures and different heights of diaphragm walls on the total flow in the foundation pit is measured and calculated; s5, performing three-dimensional seepage simulation on underground water in the foundation pit; and S6, a dewatering strategy in the foundation pit is selected. According to the construction method of the silty-fine sand layer seepage interception wall based on the river-facing three-dimensional seepage modeling, the problems that the construction period of a project is tight, precipitation is difficult, and the seepage resistance is weak are solved, the underground water level of a foundation pit is effectively lowered, precipitation differential settlement in main body construction is reduced, and it is guaranteed that the project is safely and smoothly implemented.
本发明提供了一种基于临江三维渗流建模粉细砂层截渗墙的施工方法，包括如下步骤：S1、在基坑施工区域设置降水井，测量地下水位高度；S2、通过降水井对基坑内降水，测量基坑区域的含水层渗透率；S3、进行典型段面渗漏分析；S4、测算不同水头压力、不同高度防渗墙对基坑内总流量的影响；S5、对基坑内地下水三维渗流模拟；S6、选取基坑内降水策略。本发明所述的一种基于临江三维渗流建模粉细砂层截渗墙的施工方法，该方法解决了工程的工期紧、降水难、抗渗弱等难题，有效降低了基坑地下水位、减少了主体施工中降水不均匀沉降，以保障工程安全顺利实施。
