Abstract

In order to study expansive soil (rock) retaining of Yun Gui railway, based on experience of existing railway, mass in site shear tests, including the tests in condition of underwater and without water, are carried out. In situ lateral swelling force tests of middle-strong and weak-middle expansion soil ( rock ) ,and model tests of lateral swelling force are also carried out. The following results are obtained by tests: water have great influence on the cohesion of expansion soil ( rock ), but its influence on angle of internal friction is limited. A empirical formulas for swelling pressure and moisture content are obtained by tests. The effect of sand cushion to reduce swelling force is obtained by tests.
