Depth and Width Revision of Composite Foundation Bearing Capacity
-
摘要: 地基处理的目的主要是提高地基强度和控制地基变形。根据国家行业标准《建筑地基处理技术规范》,对处理后的复合地基,修正后的复合地基承载力特征值提高不大,甚至有时比地基处理前反而降低。国家标准《建筑地基基础设计规范》与该行业标准之间对修正后的地基承载力特征值的规定在具体工程实践中产生冲突。对此进行了分析讨论,提供了初步改进建议。Abstract: Ground treatment is employed to reinforce the ground and control the settlement. The revised bearing capacity is determined by the regulation of the Technical Code of Ground Treatment of Buildings. But the revised bearing capacity of the composite foundation is far lower than the expected value. There is conflict between the state standard and industry standard regulation. The conflict is studied, opinion is proposed.
