The main achievement and recent development at home and abroad are discussed covering some research fields such as study on saline soil and its diseases control,the three-phase structure of saline soil,salt migration,engineering characteristics,and geotechnical engineering characteristics are studied on saline soil in the northwest region of China.

Analysis on treatment of peat soil foundation;

The paper mainly relys on the following four research subjects, such as the national science fund items"Study on the time effect of the properties of turfy soil in seasonal frozen region".

This article takes turfy soil in the eastern part of Jilin as the study subject,analyzing the geologic features of turfy soil on the basis of laboratory experiments.

A detail planning scheme for the research on turfy soil of the eastern part of Jilin Province was made to study the frost heave and subside disciplinarian of turfy soil in different moisture content and load effect.

After analysing the acoustic data and the difference blocks geotechnical data of the modern Huanghe estuary, we find that the differential erosion and failure behvior of soil in the slope are controlled by sedimental geotechnical properties: The counter failure ability of soil with a low clay content(<10%), high water content(30%~45%) and large void ratio(0.
