本文介绍了用真空预压法加固天津港东突堤后方辅建区超软地基的加固效果。通过现场施工情况的调查和静力触探、十字板强度资料分析,对该区地基承载力偏低的原因与第一航务勘察设计院提供的承载力值进行了商榷。同时与市建筑设计研究院在该区进行的堆载预压法加固效果从变形和强度两方面进行比较,作出了综合评价。
This paper describes the reinforcement effect of ultra-soft foundations in the auxiliary area after the east pier of Tianjin Port by vacuum preloading. Through the investigation of the site construction and the analysis of static probe and cross plate strength data, the reasons for the low bearing capacity of foundation in this area are discussed with the bearing capacity provided by the first survey and design institute of navigation. At the same time with the City Institute of Architectural Design and Research carried out in the area by the preloading pile method to enhance the effect of deformation and strength comparison, made a comprehensive evaluation.
