摘要
利用高压直剪仪和三轴电液伺服机，采用模拟土与井壁接触面的土加砼混合试样，测得了在大埋深条件下，粘土和砂土与冻结法成井井壁相互作用力学参数大小。并结合实例，介绍了所得参数在井壁破裂分析中的应用。
By using high-pressure direct shear apparatus and triaxial electro-hydraulic servocontrolled testing system, as well as soil-concrete samples contained an interface modeling the contact surface between soil and shaft wall, the mechanical parameters of interaction between clay or sand soil and shaft wall sunk by the freeze method at great depth have been measured.Moreover, taking a shaft as an example, the application of those measured parameters to the analysis of shaft wall rupture has been introduced.
