| 中文摘要:分析了长春一汽乘用车所基坑工程地质条件，对基坑支护方案进行分析论证，并对所采用的土钉墙支护方案进行设计。采用单因素分析法，在土钉倾角合理区间内，对土钉倾角进行最优设计，得出了土钉倾角对基坑边坡稳定性影响规律。本工程采用土钉墙支护的方案，短时高效地完成了工程任务节约了投资。实践证明，通过土钉倾角优化设计，在工程造价不变的情况下，大幅提升施工安全。为土钉墙支护在长春基坑工程中的应用研究提供了借鉴。 |

| Abstract:The geological conditions were analyzed for the foundation pit engineering of Passenger Car Institute of First Automobile Group in Changchun, the analysis and demonstration were made on the supporting scheme and the soil nailing wall support scheme was designed. The optimal design of soil nail inclination angle was made within a reasonable range with single factor analysis method and the influence law of soil nail inclination angle on foundation pit slope stability was obtained. The practice shows that by this soil nailing wall supporting scheme, the engineering works was completed with short-term efficiency and investment saving; by the optimization design of soil nail inclination angle, the construction safety was greatly promoted with original project construction cost. This practice provides conference to the application study on soil nailing wall support of foundation pit engineering in Changchun. |
