Investigation on the properties of compacted silty clay subjected to electro-osmosis using bender element
《Research in Cold and Arid Regions》2023年第6期253-261,共9页KangWei Tang Chuang Lin Hao Wang WeiJun Qin DeCheng Feng Feng Zhang 
supported by the National Natural Science Foundation of China(No.41971076,No.42171128)。
The moisture content of subgrade soil in seasonally frozen regions is often higher than its optimum value,leading to a decline in mechanical properties and a reduction in subgrade bearing capacity.Electro-osmosis has ...

Numerical simulation of electroosmosis in unsaturated compacted clay被引量：1
《Research in Cold and Arid Regions》2021年第5期394-407,共14页KangWei Tang Feng Zhang DeCheng Feng GuanFu Wang 
the financial support from the National Key Research and Development Program of China(No.2018YFC1505306);the National Natural Science Foundation of China(No.41971076).
The moisture content of a road subgrade in cold regions will increase after freeze-thaw cycles,resulting in subgrade strength and stiffness losses.Electroosmosis is widely used in treating saturated soft soils to decr...

Use of fly ash with no water consumption for cold regions transportation infrastructure
《Research in Cold and Arid Regions》2015年第5期619-625,共7页Gokhan Baykal 
supported by the Scientific and Technological Research Council of Turkey(TUBITAK)with two projects(INTAG 606 and INTAG 627);supported by the Bogazici University Scientific Research Program titled BAP 639
The construction period in cold regions is very short due to problems related to excavation and use of frozen soils in embankment construction, which leads to excessive deformations upon thawing. Also, handling of com...
