岩土体原位测试设备及利用该设备的测试方法
摘要：
岩土体原位测试设备，其包括与管桩形状相同的钢管，在钢管的一个端部设置有桩尖板以及用于感应桩尖板所受压力的第一压力传感器，桩尖板垂直于钢管的侧壁；沿钢管的径向方向设置一个以上侧壁摩擦筒，并为每个侧壁摩擦筒设置用于感应其所受摩擦力的第二压力传感器；侧壁摩擦筒组成所述钢管的侧壁的一部分；钢管的侧壁的一部分设置为活动侧受压板，并设置有用于感应侧受压板所受压力的第三压力传感器；在钢管的侧壁内设置有孔隙水压力计和摄像头；还包括数据收集器，第一、二、三压力传感器以及孔隙水压力计发出的电信号均由数据收集器收集。该设备能测读多种数据，方便对土体性质准确分析。本发明还公开了一种利用上述设备进行现场原位测试的方法。
摘要（英）：

The invention relates to a soil body in situ test device, comprising a steel tube with the same shape of tubular pile as well as a data collector; wherein one end part of the steel tube is provided with a pile point plate and a first pressure sensor used for sensing pressure born by the pile point plate, the pile point plate is vertical to the side wall of the steel tube; more than one side wall friction drum is arranged along the radial direction of the steel tube, and each side wall friction drum is provided with a second pressure sensor used for sensing the friction force born by the side wall friction drum; the side wall friction drum forms one part of the side wall of the steel tube; one part of the side wall of the steel tube is set to be a movable lateral compression plate and is provided with a third pressure sensor used for sensing the pressure born by the lateral compression plate; the side wall of the steel tube is internally provided with a pore pressure gauge and a camera; and electrical signals sent by the first, second and third pressure sensors and the pore pressure gauge are all collected by the data collector. The device can test and read multiple data, thus being convenient for accurately analyzing soil body properties. The invention also discloses an in situ test method applying the device.
