摘要
结合中山大学深圳校区建设工程项目,对综合服务大楼直径2.5 m边坡支护桩的工程施工技术进行了研究。经过方案比选,最终选择了采用泥浆护壁旋挖成孔施工工艺进行大直径嵌岩支护桩的施工。施工结果显示,泥浆护壁旋挖成孔技术具有良好的适用性,可为类似工程提供参考。
Combined with the engineering construction in the Shenzhen Campus of Sun Yat-sen University,the construction technology of 2.5 m diameter slope support pile of the comprehensive service building is investigated.Through the comparison and selection of the schemes,the successful application cases of the construction of large diameter rock socketed support pile under the condition of high slope and complex site,adopted by the rotary drilling technology of slurry wall protection are achieved,which can provide reference for similar projects.
