摘要
本文介绍了室内小型载荷试验的原理、设备装置及方法，据所获得的19组70多点室内与野外大小压板载荷试验对比研究，以建立的经验关系式解释出的野外载荷试验P－S曲线，经对比验证，曲线变形形态、类型及特点极为相似，结果可靠。从而提出用简易的室内小型载荷试验，可取代笨重的野外载荷试验，这对地基上非线性变形计算和建筑性能评价，是可行的具有实际意义的一种新方法。
This papet inttoduces the principle and method of the small loading test inlab. Through comparison the studies of loading test between in situ and in lab, it is possib1e toteplace tke in-situ large plate loading test with simple smaIl 1oading test in lab. It is feasible tothe nolineap deformation calculation of ground soil and the evaluation of the construct property.It is a new method with practical significance.
