Soil body shear strength testing device and soil body shear strength testing method
The invention discloses a soil body shear strength testing device, a cross plate testing section is mounted at the end part of a probe rod, and the cross plate testing section is used for forming a cross plate structure along with clockwise rotation of the probe rod after penetrating into a soil body along with the probe rod so as to shear the soil body. The static sounding test section is mounted on one side, deviating from the probe rod, of the cross plate test section, and the static sounding test section is used for penetrating into a soil body along with the probe rod and measuring soil body resistance and pore water pressure. The penetration mechanism is connected with the probe rod and used for driving the probe rod to penetrate into the soil body. The rotating mechanism is connected with the probe rod and used for driving the probe rod to rotate. The measuring mechanism is connected with the static sounding test section, the penetration mechanism is connected with the rotating mechanism, and the measuring mechanism is used for measuring values of soil resistance and pore water pressure, a value of penetration force provided by the penetration mechanism and a value of torsion provided by the rotating mechanism. According to the device, static sounding and vane testing can be carried out at the same hole site according to needs.
本申请公开了一种土体抗剪强度测试装置，其中，十字板测试段安装在探杆的端部，十字板测试段用于随着探杆贯入至土体中后，随着顺时针转动探杆形成十字板结构，对土体进行剪切。静力触探测试段安装在十字板测试段的背离探杆的一侧，静力触探测试段用于随着探杆贯入至土体中，并对土体阻力和孔隙水压力进行测量。贯入机构与探杆连接，贯入机构用于驱动探杆贯入至土体中。转动机构与探杆连接，转动机构用于驱动探杆转动。测量机构与静力触探测试段连接、贯入机构和转动机构连接，测量机构用于测量土体阻力和孔隙水压力的值、贯入机构提供的贯入力的值和转动机构提供的扭力的值。本申请的装置可根据需要在同一孔位开展静力触探和十字板测试。
