| 摘 要： | 为了探究发挥土体自身强度进行支护的规律,对某基坑进行了试验性支护设计。基坑两侧均采用组合粉喷桩重力式挡土墙支护,但压顶方式不同。开挖后基坑两侧挡土墙均产生了破坏,但破坏先后次序和破坏程度不同。分析表明：重力式挡土墙格栅内不同部位桩墙受力情形不同,因而组合采用不同工法桩体具有合理性;在验算重力式挡土墙外部稳定性的同时,还应验算墙内土体的局部稳定性。试验对该工法的理论研究与设计方法具有一定借鉴意义。 |

| Abstract: | A experimental surpporting design of deep pit is made. Both sides of the deep pit adopts combinatorial poder - jetting pile retaining wall. After excavation both sides go to failure altough the order and the degree of failure on each side is different. The analysis indicates that the various parts within the retaining wall are in various load state so it is retional to assign various pile methods. Not only the whole stability but the partial stability are necessary to check. The test has referential meaning for theory research and design access. |
| Keywords: | combinatorial method dry jet mixing pile lime gravity retaining wall deep pit stability |
