Soil body in-situ testing device and method
The invention relates to the technical field of geotechnical engineering in-situ testing, and particularly provides a soil body in-situ testing device and method.The soil body in-situ testing device comprises a combined probe, and the combined probe comprises a main probe and a sub-probe which are used in cooperation; the main probe mounted at the lower end of the lower guide rod sleeves the inner rod and is in sliding fit with the inner rod; the sub-probe is connected with the lower end of the inner rod, is positioned at the lower end of the main probe and serves as the tip part of the main probe; the sensor and the test analyzer are electrically connected; the sensor is used for measuring the relative displacement generated by the combined probe and the pressure borne by the sub-probe when the combined probe penetrates into a soil body and the spring is compressed due to stress; and the test analyzer is used for calculating the maximum penetration resistance of the combined probe and the maximum penetration resistance of the sub-probe. The method can obtain a more accurate test result, and has the advantages of being convenient to operate, improving the working efficiency, facilitating popularization and implementation and the like.
本发明涉及岩土工程原位测试技术领域，具体提供一种土体原位测试装置及方法，包括组合式探头，组合式探头包括配合使用的主探头和子探头；安装于下导向杆下端的主探头套设于内杆上、且滑动配合；子探头与内杆的下端相连，子探头位于主探头的下端、且作为主探头的尖端部；还包括电连接的传感器和测试分析仪；传感器用于测量当组合式探头贯入土体中，因弹簧受力压缩，组合式探头产生的相对位移，以及子探头受到的压力；测试分析仪用于计算获得组合式探头的最大贯入阻力，以及子探头的最大贯入阻力。本发明能得到更为精确的测试结果，还具有操作方便、提高作业效率、利于推广实施等优势。
