| 摘 要： | 针对湿陷性黄土场地上某倾斜住宅楼,设计采用钢筋混凝土托换桩加固与浸水纠偏等处理措施。利用原有3:7灰土垫层,使托换桩疏布(桩距1.8~3.9 m)与灰土垫层组成复合地基。观测数据显示,加固纠偏方案可行,技术经济效果明显,为今后类似工程提供了可资借鉴的实践经验。

| Abstract: | Aiming at a wet subsided loess site of a tilted residential building, measures have been designed and applied by using reinforced concrete underpinning piles and soaking correction. By using the original cushion of lime and soil (3:7),a composite foundation was formed by underpinning sparse piles (pile interval from 1.8 to3.9m)and lime cushion. The observational data show that the correction by reinforcement is feasible, technical and economic effect is obvious, providing experiences for future similar projects. |
