摘　　要：基于室内三轴剪切试验与天然土体的受力状态存在较大差异,从土的总应力强度指标与土的固结状态、初始固结状态、应力路径等之间的相关性出发,建立不同固结状态的土在不同试验条件下的总应力强度指标理论公式,并找出不同试验条件下的强度指标与室内常规三轴试验强度指标间的换算公式,进而解决了室内常规三轴试验在模拟天然土体的初始固结应力状态、加载路径等方面的不足。Based on some distinguish in soil＇ stress states between in labs and under the condition of nature, beginning with the total stress strength indexes＇ relationship with the consolidation states, initial consolidation states, stress path and drained conditions, this thesis gets some total stress strength indexes theoretical formulas of the different consolidation states＇soil in different lab conditions and builds some convertible formulas. Consequently it resolves lab triaxial test＇s shortage in simulating natral soil＇s initial consolidation states and stress path.
