摘要: 在软土深厚的区域,由于土层渗透系数小、强度低且软土分布不均,港口工程不宜选用天然地基。根据港口工程的地质条件,及作为钢材堆场的使用要求,分析不同地基处理方案的特点,最终确定采用高真空击密法加固地基。从设计方法、工后沉降计算、信息化施工等方面,详细介绍了该港口地基处理方法,该港口地基处理可为相近工程提供一定的借鉴作用。

Abstract: A thick, soft clay soil is deposited under a harbor project area. Due to its low permeability, low shear strength and heterogeneous distribution, no engineering structures could be constructed directly on this soil layer. Several ground improvement methods were proposed based on subsurface condition of the harbor and the purpose as the steel storage yard and the high vacuum preloading method was selected. The ground improvement design, post construction settlement estimation, informational construction aspects for the harbor construction are introduced in detail in this paper.  

Key words: high vacuum preloading method, soft soil, dynamic compaction, vacuum dewatering
