基于地基与基础等强置换、地基压力扩散原理及复合地基理论，以孤石加固法、结构加固法、复合地基与基础加固法及等强补桩法比较，分析了某建筑主体结构已施工基桩遇孤石的承载力、沉降量不能全部满足要求的处理方案，探讨复合地基加固法和等强补桩法的应用。提高土层压缩模量是复合地基加固的重要途径，合理、有效地确定地基处理范围是复合地基加固的重要环节。
基于地基與基礎等彊置換、地基壓力擴散原理及複閤地基理論，以孤石加固法、結構加固法、複閤地基與基礎加固法及等彊補樁法比較，分析瞭某建築主體結構已施工基樁遇孤石的承載力、沉降量不能全部滿足要求的處理方案，探討複閤地基加固法和等彊補樁法的應用。提高土層壓縮模量是複閤地基加固的重要途徑，閤理、有效地確定地基處理範圍是複閤地基加固的重要環節。

Based on the equal strength displacement theory of foundation and foundation, ground pressure diffusion principle and the theory of composite foundation, comparisons of boulder reinforcement method, the structure reinforcement method, composite foundation and pile foundation reinforcement method and equal strength reinforcement method were made.The treatment plan for bearing capacity and settle-ment under requirements due to boulder encountered in a foundation pile which main structure has been built was analyzed.Application of composite foundation reinforcement method and equal strength pile reinforcement method were discussed.Improvement of the soil compres-sion modulus is the important way of compound foundation reinforcement, reasonable and effective determination of the scope of the founda-tion treatment is an important part of the composite foundation reinforcement.
