STATIC LOADING TESTS ON VIBRATING GRAVEL PILE FOUNDATION IN MU US DESERT
摘要
Abstract
This paper presents the field static loading tests on Vibrating Gravel Pile Foundation in Mu Us Desert. The effective length of the gravel pile and the bearing capacity of the Vibrating Gravel Pile Foundation are studied. The test results show that the critical loads of the natural base, gravel pile, soil between piles and the compound foundation are 128 kPa, 1019. 2 kPa, 318 kPa.and 535 kPa.and the limit loads of the natural base and the soil between piles are 320 kPa and 318 kPa respectively. The limit loads of the gravel pile and the compound foundation are more than 3312.4 kPa and 2072 kPa respectively. The results also show that although the effective length of the gravel pile reaches 8m,the loads are supported mainly by the upper 4m of the gravel pile. The work of this paper makes great significance to practice of the gravel Pile Foundation in the Mu Us Desert.关键词
