摘要： 城市化的快速推进使得多种组合支护方式在基坑工程中得到越来越多应用。以北京某基坑工程为例，介绍了在限定支护条件下，根据现场实际需要和工程特点选择了土钉墙、桩锚、挡土墙等多种支护方式的组合支护型式，监测数据表明支护工程是成功的。该工程实践能够为类似的复杂条件下基坑施工难题提供解决思路，具有较强的借鉴意义。

Abstract: With the rapid development of urbanization, a variety of composite support methods have been received more and more applications in the excavation supports. This paper presents a case history of selecting the deep excavation supporting system in Beijing. Based on the project needs, a combination of several supporting systems, soil nail wall, soldier pile with ground anchor and gravity retaining wall were used. The construction monitoring data indicated that the results were satisfactory.
