摘要
目前水坠砂法缺乏相关规范指导,且工程实例较少。结合水坠砂法在土库曼斯坦巴格德雷合同区域A区改建扩能工程(80×108 m3/a原料气)砂类地基处理中的应用,介绍了水坠砂法处理地基的适用范围、工作原理、施工工艺和技术要点。干密度、动力触探和静力载荷试验的检测结果表明水坠砂法地基处理后回填土的压实系数、沉降情况和地基承载力特征值均满足设计要求,为后续类似工程提供一定技术借鉴。
Currently,the sluicing-siltation method for foundation treatment lacks relevant guidelines and has a few engineering examples.Based on the reformation project of 80×108 m3/a commodity gas in Baghdray contract area in Turkmenistan,the application scope,working principle,construction technology and technical points of the sluicing-siltation method for sandy foundation treatment are introduced.The results of dry density test,dynamic penetration test and static load test show that the compaction coefficient and settlement of backfilled soil and the bearing capacity of foundation treated by the sluicing-siltation method can satisfy the design requirements.The experience and results can be referred in subsequent design and construction under similar situation.
