| 中文摘要: |
| 苏州站改造工程中，地下连续墙作为地铁站围护结构兼做上部结构基础，属复合式承重连续墙，最大成槽深度约57 m，具有地质条件差、地下水位高、含微承压水和承压水层、空槽段深、异型连续墙多等不利因素。文中结合工程复杂地质和成槽施工工艺，分析连续墙槽壁失稳的机理以及微承压水、施工附加荷载、泥浆等对连续墙槽壁稳定性影响。制定了有效施工控制措施，取得良好效果，为同类工程施工积累了宝贵的经验。 |
| 英文摘要: |
| In the modification project of Suzhou Station, the diaphragm wall is regarded as the envelope structure and foundation of its principal structure part, belonging under composite diaphragm wall. The maximum depth of slurry trench of the diaphragm wall is 57 m. There are some harmful factors for the construction such as complicated geological situation, high water level, confined groundwater and special shape diaphragm wall. In this paper, the mechanism of stability failure is analyzed combining with the geological situation and construction technology, taking into consideration the effect of construction load, confined groundwater and slurry on the stability of trench sides of diaphragm wall. Effective construction measures are taken and good effect is achieved, and valuable experience is accumulated for the same kind of construction. |
