Research Initiation: Mitigation Measures for Small Structures on Collapsible Soils

本工作的目的是在现场条件下评价和比较两种稳定小型建筑湿陷性土剖面的新方法与传统方法。采用以下方法稳定地基：1)未经处理；2 ) pre-wettings;3) 2%水玻璃溶液预湿；4)开挖更换；5)干土强夯；6)对预湿土强夯法的性能和成本进行比较。防止小型结构倒塌和经济缓解措施，特别是在美国的大部分地区，以及收集所需的数据，是该项目带来的一些好处。

The objective of this work is to evaluate and compare under field conditions, two new methods with conventional ones for stabilizing collapsible soils profiles for small building construction. Small footings constructed on soil plots stabilized by: 1) no treatment; 2) pre-wettings; 3) pre-wetting with 2% sodium silicate solution; 4) excavation and replacement; 5) dynamic compaction on dry soil; and 6) dynamic compaction on pre-wet soil will be compared in their behavior and cost. Prevention of small structures collapse and economical mitigation measures especially in large portions of the U.S., together with the collection of needed data are some of the benefits stemming from this project.
