摘　　要：在基坑支护设计中,通过对各地规范理解总结,重点阐述了岩土抗剪强度指标的直剪试验和三轴试验指标结果的适用性。针对不同土质和基坑分析不同指标,合理选用相应土力学强度指标,使基坑设计安全经济。Based on the understanding of the different specifications,the applicability of soil shear strength which is obtained by the direct shear test or triaxial test is analyzed in foundation pit supporting design. According to soil and foundation pit design indexes,the reasonable soil mechanic indexes are selected which can ensure the foundation pit safety.
