Precipitation stopping method for foundation pit in coastal dynamic water area
The invention discloses a coastal dynamic water area foundation pit water stopping and lowering method. The method comprises the steps that the landform, the rock-soil layer distribution condition, all rock-soil layer calculation parameters and the underground water distribution condition of an engineering area are collected; obtaining the final drawdown in the foundation pit under different supply distances and the influence of different supply distances on the seepage field near the foundation pit; a flowing water supply area is divided into a supply blocking area, a supply transition area and a supply low influence area; the distance between flowing water supply of the current construction project and the foundation pit is obtained, and the area where a flowing water supply source is located is judged; when the flowing water supply source is located in the supply blocking area, a measure of blocking the supply water source is adopted for foundation pit precipitation stopping; when the flowing water supply source is located in the supply transition area, foundation pit water stopping and lowering are conducted by adjusting design parameters; and when the flowing water supply source is located in the supply low influence area, a conventional method is adopted for foundation pit water stopping and lowering. The reasonable water stopping and lowering method is selected for different flowing water supply areas, and the design and construction cost of the foundation pit is reduced while the safety of the deep and large foundation pit is guaranteed.
本发明一种临海动水区基坑止降水方法，包括：收集工程区域地形地貌、岩土层分布情况、各岩土层计算参数及地下水分布情况；获取不同补给距离下基坑内的最终降深及不同补给距离对基坑附近渗流场的影响；将动水补给区域分为补给阻断区、补给过渡区和补给低影响区；获取当前施工工程的动水补给与基坑的距离，判断动水补给源所在区域；当动水补给源位于补给阻断区时，采用隔断补给水源措施进行基坑止降水；当动水补给源位于补给过渡区时，通过调整设计参数进行基坑止降水；当动水补给源位于补给低影响区时，采用常规方法进行基坑止降水。本发明针对不同的动水补给区域选择合理的止降水方法，在保证深大基坑安全的同时，降低了基坑的设计施工成本。
