Load test method for simultaneously measuring pile-soil deformation of composite foundation
The invention relates to a load test method for simultaneously measuring pile-soil deformation of a composite foundation. The load test method comprises the following steps that S1, a pile is arranged in foundation soil to construct the composite foundation; S2, a pile measuring ruler and a soil measuring ruler are placed on the surface of the composite foundation, so that a flat plate part of the pile measuring ruler is located at the top of a pile, vertical stand columns of the pile measuring ruler are vertically upward, the flat plate part of the soil measuring ruler is located on the surface of foundation soil, and the vertical stand column of the soil measuring ruler is vertically upward; S3, a mattress layer is laid on the surface of the foundation soil, the mattress layer covers the flat plate part of the pile measuring ruler and the flat plate part of the soil measuring ruler, and the vertical stand columns of the pile measuring ruler and the vertical stand column of the soil measuring ruler penetrate out of the mattress layer; S4, a bearing plate is pressed on the mattress layer, so that the vertical stand columns of the pile measuring ruler and the vertical stand column of the soil measuring ruler penetrate out of the corresponding through holes of the bearing plate, and displacement measuring devices are arranged for the vertical stand columns of the pile measuring ruler and the vertical stand column of the soil measuring ruler; and S5, pressure is applied to the bearing plate through a pressure loading machine, the displacement of each vertical stand column is measured, the displacement obtained through the vertical stand columns of the pile measuring ruler is the pile settlement, and the displacement obtained through the vertical stand column of the soil measuring ruler is the foundation soil settlement.
本发明涉及时测量复合地基桩－土变形的载荷试验方法，该方法步骤1、将桩设置于地基土中，构建为复合地基；步骤2、将所述测桩尺和测土尺放置于复合地基表面，使得测桩尺的平板部位于桩的顶部，且测桩尺的垂直立柱垂直向上；使得测土尺的平板部位于地基土表面，且测土尺的垂直立柱垂直向上；步骤3、在地基土表面铺设褥垫层，且使得褥垫层覆盖测桩尺的平板部和测土尺的平板部，并使得测桩尺的垂直立柱和测土尺的垂直立柱均从褥垫层穿出；步骤4、将承压板压在所述褥垫层上，使得测桩尺的垂直立柱和测土尺的垂直立柱均从承压板的对应通孔穿出；针对测桩尺的垂直立柱和测土尺的垂直立柱设置位移测量装置；步骤5、通过压力加载机对承压板施加压力，测量每个垂直立柱的位移量，由所述测桩尺的垂直立柱得出的位移量为桩沉降量，由所述测土尺的垂直立柱得出的位移量为地基土沉降量。
