| 中文摘要: |
| 针对重载铁路对地基承载力要求高，沉降小的特点，依托山西中南部铁路通道重载铁路路基进行钢花管注浆加固处理以提高承载力工艺的施工，对钻机的选择与就位、钢花管的加工与安装、注浆顺序与深度进行分析，最后采用静载试验对加固区域进行承载力检测，达到了预定的效果，对类似工程施工具有一定的借鉴意义。 |
| 英文摘要: |
| With the strict requirements of heavy duty railways in bearing capability and the characteristics of being small in settlement taken into account,and based on the construction of the heavy duty railway of the Mid south Railway Passage in Shanxi Province,in which roadbed consolidation is performed by means of the holed steel tube grouting technique to improve its bearing capability,this paper analyzes in depth the choice and positioning of the drillers,the processing and fixing of the holed steel tubes,the order of the grouting processes,etc. Finally,the bearing capability of the consolidated sections is checked with static load tests,which show that the expected effects are realized. This paper may serve as a useful reference for the construction of other similar projects. |
