摘要
针对软土地基上筏式基础房屋,探讨了水平掏土法纠偏的一些理论性问题.详细分析了挖宽比φ、挖深比ξ和荷载偏心率ε对基底应力的影响及其规律,提出了掏土纠偏的设计计算方法,并简要介绍了一个工程实例,可供掏土纠偏设计、施工时参考应用.
Some basic problems of rectifying settlement of mat foundation under a building setting on soft clay by drawing-out soils horizontally are studied. The influence of width ratio φ, depth ratio ξ as well as load eccentricity on base pressure and its regulars are expounded. A design method of rectifying settlement is suggested, and an engineering example is briefly introduced, which may be useful for design and working.
