摘要
针对架空输电线路工程杆塔基础的荷载特点和软土地区的特殊地质条件,开展了微型沉井基础在上拔、下压、水平、上拔与水平联合荷载工况下的承载特性真型试验研究,将得到的微型沉井基础极限承载力与理论设计值进行了对比分析,两者结果比较接近,表明相关理论计算公式和参数取值是可行的,分析结果验证了微型沉井基础设计选型的合理性和可靠性。
According to the load characteristics on tower foundation of overhead transmission line project and the special geological conditions of soft soil area,in-situ experimental study on bearing characteristics of micro caisson foundation were conducted,including uplift,compressive,horizontal as well as uplift and horizontal loading conditions.The ultimate bearing capacities test value of the micro caisson foundation were obtained and compared with the theoretical design values.They were comparatively close,which showed that the relevant theoretical formula sand parameters were feasible.As a result,the rationality and reliability of the design and selection of the micro caisson foundation were verified.
