摘要
沱江由于河道淤积、防洪排涝体系不完整、堤防工程建设标准低和工程年久失修等原因,雨季洪灾隐患突出,尤其是沱江硚山河大桥兴建后对河道防洪的影响和堤防的稳固性提出了更高的挑战。在水文分析的基础上,建立了基于有限元计算的堤防渗流分析模型,模拟分析了硚山河大桥紧邻堤防工程在大桥兴建前后不同工况下的堤坡的抗滑稳定性,提出了综合评价意见。
Because of the river channel siltation,incomplete flood control and drainage system,low levee construction standard and long-term project disrepair and other reasons,the flood hazard in rainy season is prominent,especially after the proposed project,the impact of river channel flood control and the stability of levee pose a higher challenge.On the basis of hydrological analysis,the seepage analysis model of levee based on finite element calculation is established.Under different working conditions,the anti sliding stability of the levee slope before and after the construction of the project connecting the levee of the proposed project is simulated,and the flood control impact and comprehensive evaluation opinions after the project are put forward.
