微型载荷试验的依据与方法

由于载荷试验是求地基承载力的最佳途径，现代分析方法要求在较大深度以及水下取得大量数据。该文叙述用三倍于压板直径的环刀取原状土，按载荷试验的边界条件，在室内进行微型试验求地基承载力，同时用静力触探求变形模量。其结果用于确定基础类型，并用有限元法求地基变形。

THE BASIS AND METHOD OF THE MINIATURE PLATE LOAD TEST

Owing to the fact that the plate load test has been proved to be the best way to determine the bearing capacity of the ground soil, and the modern analysis method requires a large amount of data at greater depth and also underwater, the paper states the method using a sampling ring tbree times the diameter of the bearing plate to take tbe undisturbed sample preserving tbe in-situ lateral stress. The miniature plate load test is conducted in laboratory to obtain the bearing capicity under a boundary condition similar to the in-situ plate load test. At the same time, the deformation moduli can be obtained by the static cone penetration test.The results are applied to the determinatiou of foundation types and the ground deformation by finite element method.
