以佛山市城市轨道交通2号线登州站详勘为例,将在勘察中常用的确定土的抗剪强度指标的直剪试验、三轴试验、无侧限抗压强度试验和原位十字板剪切试验进行对比,结合土体的应力状态、应力历史等进行分析,联系地铁勘察、设计、施工的实际情况,提出最优的抗剪强度参数选取的建议。 Taking the detailed survey of Dengzhou station of No.2 line of urban rail transit in Foshan as an example, the direct shear test, triaxial test, unconfined compressive strength test and in situ cross The shear tests are compared with each other. Based on the stress state and the stress history of the soil, the optimum conditions of shear strength parameters are proposed according to the actual situation of the subway survey, design and construction.
