摘　　要：结合深圳大学西丽校区施工实际,对开挖土层主要在花岗岩残积地层中且周边环境复杂的超大型基坑施工技术进行了研究。通过采用围护桩施工、锚索施工、旋喷施工、喷射混凝土施工、土方开挖等针对性措施,确保了施工顺利进行,积累的经验可为类似工程提供借鉴。Combined with the construction practice of Xili campus of Shenzhen University, this paper studies the construction technology of super-large foundation pit where the excavation soil layer is mainly in granite eluvium and the surrounding environment is complex. By adopting targeted construction measures for support pile, anchor cable, jet grouting, shotcrete, earthwork excavation, etc., the smooth construction is ensured, and the accumulated experience can provide reference for similar projects.
