Three-dimensional water seepage prevention and control method for gully high fill engineering
The invention belongs to the technical field of collapsible foundation reinforcement, and relates to a gully high-fill engineering three-dimensional water seepage prevention and control method which comprises the steps that the water seepage position of a slope is determined; determining the underground water seepage field condition of the filled valley, a possible water seepage path and the position of a specific exposure point; calculating the supplied rainfall, determining the actual catchment area of the stratum, basically determining the annual catchment amount of the slope stratum, and measuring the volume of lateral incoming water at different positions; determining the designed height and range of a slope body water seepage material layer; the graded broken stone thickness of the bottom of the valley is designed; a three-dimensional anti-seepage design method is adopted, the hidden danger of water seepage of the filling body is eliminated, it is ensured that the filling body is not threatened by surrounding water seepage, and the problem that after filling is completed, slope water seepage causes large-area differential settlement of a filling project, and project operation is difficult is effectively solved; therefore, the filling engineering quality is guaranteed, large-area differential settlement in the later period is avoided, and obvious economic benefits and social benefits are brought.
本发明属于湿陷性地基加固技术领域，涉及一种沟壑高填方工程立体渗水防治方法，包括：确定坡体的渗水位置；确定填方后沟谷的地下水渗透场情况、可能的渗水路径以及具体出露点的位置；计算接受补给的雨量，确定地层实际汇水面积，基本确定坡体地层的年汇水量，测算不同位置侧向来水的体量；确定坡体渗水料层设计的高度和范围；设计沟谷底部的配级碎石厚度；本发明采用立体防渗设计方法，将填方体的渗水隐患排除，确保填方体不受四周渗水威胁，有效避免了填方完工后坡体渗水导致填方工程出现大面积不均匀沉降，造成工程运行困难的问题；因此，本发明保证填方工程质量，避免后期出现大面积不均匀沉降，带来明显的经济效益和社会效益。
