软土地区静态钻孔结节桩承载力

Static Bored Nodular Pile Bearing Capacity in Soft Soil Area

静压钻孔结节桩是一种新型的桩基,由预制结节桩和周围的水泥土组成。该复合桩具有相对较高的承载能力,并且在施工过程中通过使用这种类型的桩将大大减少泥浆污染。为了研究该桩的承载力,进行了一组试验,以对这种新桩与钻孔桩进行对比。通过安装在桩上的应变仪测量预制结节桩的轴向力,分析结节桩的轴力分布和周围土壤支撑的表面摩擦力,然后利用ABAQUS建立三维模型。

Static pressure drilled knot pile is a new type of pile foundation, which consists of prefabricated knot piles and surrounding cement soil. The composite pile has relatively high bearing capacity and is used during construction. The pile will greatly reduce mud pollution. In order to study the bearing capacity of the pile, a set of tests was carried out to compare the new pile with the bored pile. The axis of the precast knot pile was measured by a strain gauge mounted on the pile. To analyze the axial force distribution of the nodule pile and the surface friction of the surrounding soil support, and then use ABAQUS to establish a three-dimensional model.
