摘要
基于土工合成材料在盐渍土地基中耐腐蚀的特点,采用一种适用于超强盐渍土地区的防腐蚀新技术——大直径袋装混凝土灌注桩(简称"布袋桩"),以察尔汗盐湖的察格高速项目为依托,对布袋桩这种新工艺在施工过程中的问题进行总结、分析和研究,提出了解决和预防性对策,对混凝土浇注前防腐袋的完整性给出了较科学的控制方法。
Given that the geosynthetics are characterized by their corrosion resistance in salty soil, bagged concrete piles （referred to as BCPS） with large diameters were applied to super saline soil areas. Based on the project of Qarhan-Golmud Expressway starting from Qarhan Salt Lake, problems that might occur during the construction of bagged concrete piles were studied and summarized, and preventative measures and solutions were proposed. Reasonable ways to maintain the completeness of the preservative bags before pouring the concrete were also mentioned.
