| 中文摘要:汉中佳苑小区新建住宅楼位于河流高漫滩地带，所选择地基持力层地层沉积年代较新，固结不充分。住宅楼建成后，由于地基不均匀沉降致使建筑出现裂缝，通过对现场工程地质条件的研究，对多种方案进行了经济技术可行性的比选，决定采用压力注浆方法，达到控制沉降、保护建筑的目的。根据施工场地主要位于建筑内部的特点，合理选用气锤击入花管注浆施工工艺，解决了狭窄场地条件下的施工难题，同时避免了采用静压桩和旋喷桩施工对建筑周边环境以及对基础本身的破坏。 |

| Abstract:There are cracks in new built residential buildings due to the uneven settlement of the foundation. Based on the geological conditions and construction site investigation, pressure grouting was selected to protect the buildings. To solve the construction difficulties in narrow site, the technology of grouting through a perforated tube shot into ground by an air hammer was selected, which also avoided the destruction to environment around existing buildings and the foundation by static pressure pile and jet grouting pile construction. |
