摘要
简要介绍了螺纹桩技术,并在工程实例的基础上,对螺纹桩承载力的静载和高应变检测进行了对比分析。从检测结果可知,螺纹桩成桩时桩身质量可靠,承载力高,应用前景广阔。螺纹桩承载力高应变检测结果比静载结果高11%~20%,在工程桩验收和应用中应引起重视。
The technology of screw pile was introduced in this paper,on the basis of project example,the static loading test and dynamic high strain test for bearing capacity of screw pile were compared and analyzed.From the test results it is known that the pile body quality is very good and the bearing capacity is high when pile is formed,and it has a wide prospect.The bearing capacity of the screw pile from the high strain test result is 11%~20% than that from static load test result,this should be stressed in the application and acceptance of engineering pile.
