PHC管桩在复杂软土地基条件下的设计与施工应用研究

以实际工程为依托,研究了PHC管桩采用静压式施工技术在具有软弱下卧层的持力层中并且受环境场地影响无法穿越此软弱夹层的复杂地质条件下的设计与施工。提出了工程的解决方案,并利用反射波法与高应变法对桩基进行检测,通过检测结果分析证明所设计的PHC管桩满足规范要求。可为类似工程设计与施工提供参考与借鉴。

Application of Design and Construction with PHC Tube Pile Foundation to Complex Soft Soil Based Conditions

Relying on practical engineering,the use of static type PHC pile in construction technology on a weak underlying layer and the bearing stratum in the environment where the impact can not be affected by the weak through the dissection under the complicated geological conditions,was studied,inclusive of the design and construction researched.The solution to the engineering project was proposed.Also,the application of wave method and high-strain to reflection was made to the piles detection.The analyses of test results demonstrated that the adoption of PHC pile designed met with the code requirements.This study presents reference and suggestions for the similar projects and their design as well as their construction.
