Hogging moment compensation type existing shallow foundation reinforcing method
The invention relates to the technical field of building foundation reinforcement, in particular to a hogging moment compensation type existing shallow foundation reinforcement method which sequentially comprises the steps that an existing foundation to be reinforced is determined; calculating the bearing bending moment MR and the shearing force VR of each existing foundation; newly-added pile parameters are selected, and load guiding is conducted on the upper structure of the existing foundation; the size of the combined bearing platform is determined, the pile number and the pile position are determined, and hogging moment is generated at the tops of newly-added piles on the periphery of the combined bearing platform; calculating a bending moment design value M1 and a shearing force design value V1 of each existing foundation; mR is compared with M1, VR is compared with V1 until MR is larger than M1, and VR is larger than V1. The method has the effect of effectively improving the bearing capacity of the existing foundation under the clearance limited condition.
本申请涉及建筑基础加固的技术领域，尤其是涉及一种负弯矩补偿型既有浅基础加固方法，依次包括：确定拟加固的既有基础；计算各既有基础承载弯矩MR和剪力VR；选择新增桩参数并对既有基础上部结构导荷；确定联合承台尺寸并确定桩数和桩位，使联合承台外围新增桩顶部产生负弯矩；计算各既有基础弯矩设计值M1，剪力设计值V1；对比MR和M1、VR和V1直至MR＞M1、VR＞V1。本申请具有在净空受限条件下有效提高既有基础承载力的效果。
