Use method of deep load test equipment in open caisson construction period
The invention provides a use method of deep load test equipment in an open caisson construction period. The equipment comprises a counter-force device, a loading device, a displacement limiting device and a displacement measuring device. The method comprises the following steps of: arranging the displacement measuring device on the loading device; connecting the loading device with a second end of the counter-force device; arranging the displacement limiting device on the outer side wall of the counter-force device; extending the second end of the counter-force device into an open caisson test hole, and connecting a first end of the counter-force device with an open caisson main body structure; operating the loading device to test a test soil body in the open caisson test hole; and observing the displacement of the loading device in the vertical direction through the displacement measuring device. According to the use method, the real displacement of a bearing plate can be directly obtained, and test errors caused by test depth and deformation of the counter-force device are greatly reduced.
一种沉井施工期深层载荷试验设备的使用方法，所述设备包括：反力装置、加载装置、位移限定装置和位移测量装置，所述方法包括步骤：将所述位移测量装置设置于所述加载装置上；将所述加载装置与所述反力装置的第二端连接；将所述位移限定装置设置于所述反力装置外侧壁上；将所述反力装置的第二端伸入沉井试验孔中而第一端与沉井主体结构连接；操作所述加载装置对所述沉井试验孔中的试验土体进行试验；通过所述位移测量装置观察所述加载装置的竖直方向位移量。本申请可以直接获取承压板的真实位移，大大减少了由于试验深度以及反力装置变形造成的试验误差。
