什邡市某6层砖混结构住宅楼，主体完工4个月后底层局部墙体出现裂缝。经分析，该建筑局部地基为软土，其含水量大、渗透性差，原设计采用的振冲法处理效果差，从而导致局部地基承载力不足、地基沉降量大且不均匀。针对墙体裂缝原因，采用灰土桩加固软土地基，同时采用钢筋混凝土梁加固基础，加固效果良好。

Cracks were emerged from partial ground-floor walls of a six-floor residential building with a masonry-concrete structure in Shifang, 4 months after the main body had completed. According to analysis, it was soft soil in the local foundation of this building, with large water content and poor permeability, the vibroflotation reinforcement effect was poor from the original design, resulted in insufficient carrying capacity of local foundation, and large and uneven of the foundation settlement amount . Based on these reasons, favourable effects of foundation stabilization are arisen from consolidated soft soil with lime-soil piles and reinforced foundation by applying reinforced concrete beams.
