安全厚度
Examples
- Study on safe thickness of rock mass at end of bridge foundation ' s pilein karst and worked - out mine area
岩溶及采空区桥梁桩基桩端岩层安全厚度研究 - In this paper , combined with the research project " study on the design , construction and quality monitoring of foundations in karst and mined - out regions along tanshao highway " financed by the department of communication of hunan province , a deep analysis has been made to find out the factors influencing the safe thickness of bearing stratum under the pile tip in karst region . three simplified models are set up to calculate the safe thickness , from which empirical calculation formulas are deduced . and a few important conclusions drawn from the discussion can be used to guide engineering practice , which are also valuable materials for the revision of current criterions later
本文结合湖南省交通厅“潭邵高速公路岩溶及采空区路、桥基础设计施工与质量监控方法研究”研究课题，以潭邵高速公路为工程依托，通过深入分析岩溶区基桩桩端持力层安全厚度的影响因素，提出了桩端持力层安全厚度计算的三类简化模型，以此为基础，推导出了桩端持力层厚度计算公式，并通过讨论得到了可用于指导工程实践的几点重要结论，可供今后规范的修改参考；本文针对岩溶地区的特殊情况，提出了岩溶区桩基设计方法及具体设计步骤，并借鉴国内外岩溶区桩基的成功经验，提出了岩溶区桩基设计处理几种特殊方法，可供同类工程借鉴；另外，本文通过具体的工程实践，系统总结了岩溶区桩基施工技术及常遇问题的处理方法。
