Abstract: This paper presents the calculation method of pile body compression deformation with respect to BOTDR based on the load transfer analysis,and analyzes the law of pile body compression and deformation of over-length bored pile under pile top load in the static load test in combination with an engineering case.According to the comparison of the relevance between calculated value and observation value of pile compression and deformation,the validity and accuracy of this method is validated. 更多还原
