裂土三向胀缩性的室内研究

LABORATORY INVESTIGATIONS OF THREE-DIMENSIONAL SWELL-SHRINKING CHARACTERISTICS OF EXPANSIVE SOILS

本文主要介绍利用三向胀之缩特性仪来研究一些典型裂土的各向异性,找出水平膨胀力和垂直膨胀力之间的关系;变形和膨胀力之间的关系以及湿胀干缩循环膨胀力的变化。

This paper mainly introduces the application of a three-dimensional sivellshrinking characteristic apparatus to the study of the anisotropism of some typical expansive soils(or fissured clay). With purpose of finding the relations between horizontal and uertical swelling pressures, the relations between swelling pressures and deformations, and the changes of swelling pressures of damp-drying cycles of specimens.
