通过Plaxis 3D Tunnel有限元软件对室内纯剪试验,同轴电缆—注浆体与土体相互作用试验进行了有限元分析,通过反算确定了同轴电缆、注浆体的本构参数。并对实际边坡中同轴电缆—注浆体—土体共同作用的情况进行了分析,指出当注浆体的强度为边坡土体强度的1到5倍时,同轴电缆的灵敏度将达到最佳,采集的数据将会最可靠。 Through the Plaxis 3D Tunnel finite element software, finite element analysis of the pure shear test in the room, the test of the interaction between the coaxial cable and the grouting body and the soil was carried out, and the constitutive parameters of the coaxial cable and grouting body were determined by back calculation. And the co-action of the coaxial cable-grouting body-soil in the actual slope is analyzed. It is pointed out that when the strength of the grouting body is 1 to 5 times of the soil strength of the slope, the sensitivity of the coaxial cable To achieve the best, the data collected will be the most reliable.
