介绍了南昌地区某高层住宅基础采用全夯桩替代嵌岩桩的设计过程。与传统嵌岩桩相比,全夯桩具有施工工艺简单、施工速度快及工程造价低等优点。并对全夯桩进行了桩基检测及沉降观测,结果表明其桩身质量、桩基承载力及桩基沉降均满足规范要求,从而验证了全夯桩作为高层住宅基础的安全可靠性和经济合理性,拓宽了全夯桩在高层建筑基础中的应用范围。
This paper introduces the design process of using all-rammer pile instead of rock-socketed pile in the foundation of a high-rise residential building in Nanchang. Compared with the traditional rock-socketed pile, the full-rammed pile has the advantages of simple construction process, fast construction speed and low construction cost. The test results of pile foundation and settlement show that the pile mass, pile bearing capacity and settlement of pile foundation meet the requirements of the code, which verifies the safety and reliability of the fully-rammed pile as the foundation of high-rise residential buildings and economy Rationality, broaden the range of application of fully rammed piles in the foundation of high-rise buildings.
