| 中文摘要: |
| 阐述的深圳地铁民治站临近既有线平南铁路，存在着严重的偏压问题。为确保平南铁路的运营安全和施工安全，施工时平南铁路侧路基加固采用钢管桩和袖阀管注浆。为确保基坑安全连续墙设计优化为1.2m厚,同时增大入岩深度，深基坑开挖时严格遵守“竖向分层、纵向分段、随挖随撑”的原则。 |
| 英文摘要: |
| This paper concerns the construction of Minzhi Metro Station which has a serious eccentric compression problem due to the adjacent existing Pingnan Railway. To ensure the operation safety of Pingnan Railway and the safety of construction, the steel pipe pile and sleeve valve pipe grouting are adopted to strengthen the embankment on the side of Pingnan railway, meanwhile designed width of the diaphragm wall is optimized to 1.2 m and the designed depth of entering rock is increased. The excavation of deep foundation pit must obey such rules as upright slice, longitudinal divisions, and rapid bracing after excavation. |
