Rock-soil in-situ testing method
The invention discloses a rock-soil in-situ testing method which is characterized in that a rock-soil in-situ tester is arranged, a probe is fixedly arranged at the bottom of a vertical probe rod, the probe is a lateral pressure probe, and an inner cavity of the probe is a pressure chamber which is communicated with an external gas circuit and can be used for inflation or exhaust control; the pressure chamber consists of rigid bodies on three side surfaces and an elastic membrane on one side surface; the elastic membrane forms lateral displacement along with the pressure change of the pressure chamber; a displacement detection mechanism of the elastic membrane is arranged in the pressure chamber; according to the rock-soil in-situ testing method, the point position pressure of the preset depth is obtained according to the displacement detection signal of the displacement detection mechanism and the pressure signal corresponding to the pressure chamber and used for judging the mechanical property of soil at the preset point position, and point position testing of the preset depth is achieved. The method is particularly suitable for route geological exploration and is used for judging the physical and mechanical properties of rock and soil, thereby providing a basis for engineering construction.
本发明公开了一种岩土原位测试方法，其特征是：设置岩土原位测试仪，是在竖向探杆的底部固定设置探头，探头为旁压探头，探头的内部空腔是与外部气路相通、可进行充气或排气控制的压力室，压力室是由三个侧面的刚性体和一个侧面的弹性膜片构成，弹性膜片随着压力室的压力变化形成侧向位移；在压力室中设置弹性膜片的位移检测机构；岩土原位测试方法是根据位移检测机构的位移检测信号与压力室相对应的压力信号获得预定深度的点位压力，用于判别预定点位土的力学性质，实现预定深度的点位测试。本发明尤其适于路线地质勘探，用于判断岩土的物理力学性质，为工程建设提供依据。
