| 摘 要： | 设计一种岩土工程测量中基坑支护结构荷载度量方法。通过对静止土压力计算，建立位移增加后土的相互作用方程，并通过多支点结构嵌固深度计算、弹性支点计算、结构计算3个方面对基坑支护结构内力和变形计算，在此基础上，采用增量法与总量法求出施工阶段体系的实际内力和位移值，以此完成岩土工程测量中基坑支护结构荷载度量。实例分析结果表明，此次研究的基坑支护结构荷载度量方法能够准确分析出基坑开挖过程中支护结构的荷载情况以及施加车辆荷载后支护结构荷载情况，证明此次研究的方法能够真实反映出支护结构的荷载情况。

| Abstract: | In this paper，a load measurement method of foundation pit supporting structure in geotechnical engineering measurement is designed.Through the calculation of static earth pressure，the interaction equation of soil after displacement increase is established，and the internal force and deformation of foundation pit supporting structure are calculated from three aspects:embedded depth calculation of multi fulcrum structure，elastic fulcrum calculation and structural calculation.On this basis,the actual internal force and displacement of the system in the construction stage are calculated by incremental method and total quantity method.Thus，the load measurement of foundation pit supporting structure in geotechnical engineering measurement is completed.The example analysis results show that the load measurement method of foundation pit supporting structure in this study can accurately analyze the load of supporting structure in the process of foundation pit excavation and the load of supporting structure after vehicle load is applied，which proves that the method of this study can truly reflect the load of supporting structure. |
