城市下穿道路的U槽与挡墙方案研究

Study on U-groove and Retaining Wall Schemes of Urban Underpass Road

通过对城市道路下穿规划轨道交通停车场的设计分析,对下穿方案中U型槽和挡墙加盲沟的选取进行了研究。探讨如何根据道路周边建设条件、地下水情况、土质情况等,研究U型槽和挡墙加盲沟两种方案的适用性,选择合理可行的方案,确保设计合理、工程安全。

Based on the design analysis of urban road underpassing planned rail transit parking lot,the selection of U-groove,retaining wall plus blind ditch in underpass scheme is studied.How to study the applicability of U-groove and retaining wall plus blind ditch schemes is discussed according to the road surrounding construction conditions,groundwater conditions,soil conditions,etc.The selection of reasonable and feasible schemes can ensure the reasonable design and the engineering safety.
