摘要： 随着工程建设的快速发展，城市地下空间开挖逐步向深大方向发展，且周边环境越来越复杂，而深基坑支护方式作为城市地下空间工程施工的关键部分，深基坑支护设计也面临不同选择，不同的基坑支护设计方案对基坑工程的安全性、经济性和周边环境都有重要影响。以湖北省武汉市某地下精密实验室基坑为研究对象，从整体优化的理论出发，在综合考虑周边建筑和环境地质条件的基础上，对基坑支护设计方案的适用性、安全性和经济性进行评定，对不同基坑支护设计方案进行比选，对基坑支护设计方案进行优化，找出最优基坑支护设计方案，并为类似工程提供参考。

Abstract: With the rapid development of engineering construction, urban underground space excavation depth is gradually increased, and the surrounding environment is becoming increasingly complex. As a key part of the urban underground space engineering construction, deep excavation support design also faces different choices. Different excavation support design options have a significant impact on the safety, economy, and surrounding environment of foundation excavations The case history of the deep excavation of an underground precision laboratory in Wuhan, Hubei Province is presented in this paper. The paper starts from the theory of overall optimization and considering the surrounding buildings and environmental geotechnical conditions of the deep excavations. The applicability, safety, and economy of several excavation support design options are evaluated. Different excavation support design options are compared and selected. The excavation support design is optimized.

Key words: Deep Excavation, Excavation Support, Plan Optimization
