中文摘要：
本文以荷载传递分析法为基础,推导了基于BOTDR桩身压缩变形的计算方法,并结合工程实例,分析了静载荷试验中桩顶荷载作用下超长桩桩身压缩量和变形规律。通过对比桩基压缩变形的计算值与实测值的相关性,验证了该方法的有效性和准确性。
英文摘要：
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.
