Experimental Study on Bearing Capacity of Cast-in-place Bored Pile with Self-balanced Method
摘要
Abstract
Based on the pile foundation engineering of Tianshui No. 1 Bridge in Gansu, self-balance method is used to carry out bearing capacity test for two piles under the same geological conditions. Through analysis of the data measured in the field, the Q-S curves of the upper and lower section of the two piles, skin friction of pile in the various soil layers, and the resistance at the pile end are obtained. Then the results obtained by self-balance method are converted into traditional static load test results. The converted Q-S curves approximately develops as a straight line without obvious downward turning or bending section. The bearing capacity of pile foundation does not reach the limit state and has a certain safety reserve.关键词
