中亚某国扩建项目砂土地基处理方法研究

中亚某国家的天然气处理厂扩建项目，位于沙漠腹地，拟建场地地层为细砂。虽然需要处理的砂土地基厚度比较大，但结合该国家的实际情况，排除了强夯法等常见的处理砂土地基的方法，采用水坠砂的方法，对场地的砂土地基进行了处理，然后利用载荷试验、标准贯入试验、重型动力触探试验等方法来检验地基处理的效果，最终三种检测方法的统计数据显示，地基处理的结果满足了设计的要求，说明水坠砂法不仅适用于浅层砂土地基的处理，对于大厚度的砂土地基也是有效的。

Loose Sand Improvement for a Central Asia’s Natural Gas Facility Expansion Project

This paper presents soil improvement method of loose fine sand soil in the deep desert area of an arid Central Asia country for the natural gas facility expansion project. The proposed site required a very deep treatment depth. In addition to dynamic compaction and other conventional local available soil improvement methods for the arid fine sandy soils, the water submerging method was introduced in this project. The results of the water submerging method treatment at the proposed site was examined by the late loading tests, standard penetration tests and heavy dynamic cone penetration tests. The test results of all three methods showed that the soil improvement method as acceptable and it is concluded that the water submerging method was successful in treating the arid fine sandy soils.

In addition to dynamic compaction and other conventional local available soil improvement methods for the arid fine sandy soils, the water submerging method was introduced in this project.

The test results of all three methods showed that the soil improvement method as acceptable and it is concluded that the water submerging method was successful in treating the arid fine sandy soils.
