Abstract

One of the most recognized geotechnical hazard which causes dramatic life lost and serious damages to different structures, are the collapsible soils under the foundation of structures. This problem becomes more critical when water is seeped or induced to the soil structure because collapsible soils are metastable and they have an open structure Khoda Afarin main canal is a major conveyance canal which is located and is under construction in Moghan and Khoda Afarin region pass throw East Azerbaijan and Ardabil provinces in IRAN. Presence of collapsible soils in some portion of this canal bed has brought the necessity of study and treatment of this problem to the point of view. The paper takes a brief view on correlation with liquid limit and dry density test. According to the results obtained from correlation between liquid limit and dry density and practical steps have been under taken during the project implementation, such as prepounding, it was observed that effect of moisture due to prepounding sudden changes in soil volume which is the one of collapsible soils characteristic have taken place. There for it can be concluded that application of correlation between liquid limit and dry density is logical and acceptable.

Use of Liquid Limit and Dry Density Test Method for Collapsible Soil Identification

Chicago, Illinois

One of the most recognized geotechnical hazard which causes dramatic life lost and serious damages to different structures, are the collapsible soils under the foundation of structures. This problem becomes more critical when water is seeped or induced to the soil structure because collapsible soils are metastable and they have an open structure Khoda Afarin main canal is a major conveyance canal which is located and is under construction in Moghan and Khoda Afarin region pass throw East Azerbaijan and Ardabil provinces in IRAN. Presence of collapsible soils in some portion of this canal bed has brought the necessity of study and treatment of this problem to the point of view. The paper takes a brief view on correlation with liquid limit and dry density test. According to the results obtained from correlation between liquid limit and dry density and practical steps have been under taken during the project implementation, such as prepounding, it was observed that effect of moisture due to prepounding sudden changes in soil volume which is the one of collapsible soils characteristic have taken place.
