DERIVE LATERAL EARTH PRESSURE COEFICIENT AT REST BY FLAT DILATOMETER TESTS AT HANGZHOU

The Flat Dilatometer Test (DMT) have a lot of virtues. DMT has already been used somewhere in our country. However, the regionally otherness of geotechnical engineering itself, other regions' results and experiential formula can not be fully applied. After compared with the researching status, we amend the theoretical formula of in-situ initial horizontal stress, then gets the expression of Hangzhou. Compared with the data and values from the soil tests of subway projects in Hangzhou, and provide it can be used well in Hangzhou.
