岩溶发育地区物流厂房建筑结构基础方案比选

Comparison and Selection of Structural Foundation Schemes for Logistics Plant Buildings in Karst Developed Areas

  • 摘要: 为应对在岩溶发育地区工程建设的特殊需要,本文归纳总结了岩溶发育地层基础方案选型总体思路。以某物流厂房类建筑工程为例,针对该类型项目大层高、大荷载、大柱跨等特点,结合项目具体的地质条件,开展了基础方案的比选分析,旨在为类似工程提供科学合理的解决方案。结合项目具体地质条件,对浅基础、管桩基础及灌注桩基础方案进行了综合对比分析。通过技术可行性、经济合理性和施工安全性等多维度的评估,确定最优基础方案。经过详细的技术和经济比选,得出在岩溶发育地层中,高层物流仓库类建筑采用灌注桩基础方案为最优解。基于项目施工实践,总结提出了岩溶地区溶土洞处理办法及灌注桩施工过程的控制要点。这些研究成果为类似岩溶地区工程建设提供了重要的参考借鉴,有助于提高工程设计与施工的安全性和经济性。

     

    Abstract: To meet the special needs of engineering construction in karst developed areas, the overall idea for selecting basic schemes for karst developed strata has been summarized.Based on a case study of a logistics factory building project, which has the characteristics of high floor height, large load, and large column span, and combined with the specific geological conditions of the project, a comparative analysis of the basic scheme was carried out,intended to provide scientific and reasonable solutions for similar projects.Based on the specific geological conditions of the project, a comprehensive comparative analysis was conducted on shallow foundation, pipe pile foundation, and cast-in-place pile foundation schemes.Determine the optimal foundation plan through multidimensional evaluations such as technical feasibility, economic rationality, and construction safety.After detailed technical and economic comparisons, it was found that the optimal solution for high-rise logistics warehouse buildings in karst development strata is to adopt the cast-in-place pile foundation scheme.Based on project construction practice, this paper summarizes and proposes methods for treating karst soil caves and key control points for the construction process of cast-in-place piles in karst areas.These research results provide important reference for engineering construction in similar karst areas, and help to improve the safety and economy of engineering design and construction.
