近海回填基上预制桩施工质量缺陷研究

On Quality Defects in Constructive Process of Prefabricated Stake Driven into Foundation Ground in Off-shore Area

近海回填基具有自身独特的性质,在其上进行预制桩施工质量控制难度大,出现质量缺陷的频率高.该文对近海回填基上预制桩施工中经常遇到的几种主要问题进行了分析,并结合自己的实践经验和目前有关科研成果提出了处理对策.

Foundation ground treated with filling method in off-shore areas has its unique characteristics. However, it is very difficult to control the quality while forming prefabricated stake foundations. So quality defects often appear in the process of its construction. This paper analyzes the reasons which cause the common problems in constructive process of prefabricated pole driven into foundation ground treated with filling method in off-shore areas, and puts forward handling methods and measures according to practical experience and related achievements in scientific research.
