摘要
随着我国高层建筑的迅猛发展,桩基础的应用也日益广泛。冲孔桩具有冲孔直径大、深度深,施工成本低,操作方便,桩端能可靠进入持力层,单桩承载力大等特点,在高层建筑桩基础中被广泛应用。本文通过理论计算和数值模拟分析,对岩溶地区冲孔灌注桩的荷载传递机理及溶洞顶板力学特性等方面进行了较为系统的研究,得出了一些重要结论,为该技术在实际工程的推广应用提供理论依据和技术指导。
With the rapid development of China's high - rise buildings, the application of pile foundation is increasingly widespread. The punched cast - in - situ piles have the advantages of a large punching diameter, a deep depth, a low construction cost, and an easy operation, and a large single pile capacity. Theoretical calculation and numerical simulation analysis, some important conclusions are drawn as the theoretical basis and technical guidance for the promotion and application of the technology in the actual projects.
