摘要
平板载荷试验在地基承载力检测中有较广泛的应用,常见的天然地基与复合地基的平板尺寸与堆载量较小,采用钢板与普通堆载方法进行;刚性桩复合地基一般需要较大尺寸的平板且试验荷载也较大,需根据荷载及千斤顶的布置进行平板的设计制作,现场检测均存在一些关键技术难题。本文通过某预制管桩复合地基平板载荷试验的成功案例,总结大型平板载荷试验检测操作步骤与应注意的问题,为类似工程提供参考。
The plate load test is widely used in bearing capacity of foundation,the size of plate is small and the load is low in normal natural foundation and composite foundation,but the large size of plate and high load are used in composite foundation of rigid piles. Successful large plate load test case is given to summarize the problems needing attention in the large scale plate loading test and steps which can be used as the relevant reference of large plate testing.
