Based on indoor compression test material of high liquid limit clay about Ji-He expressway,analyzed the relationship among compression modulus,compression coefficient,cuts modulus and resilience modulus of high liquid limit clay of the Yellow River alluvial plain with its moisture content and dry unit weight,and their changing rules.The results show that in a certain dry unit weight condition,free expansion ratio of high liquid limit clay is decreasing with the increasing of natural moisture content, however, in a certain moisture content condition,the free expansion ratio is increasing with increase of the dry unit weight.Compression modulus decreases along with the rising of moisture content,while increases to gether with the increasing of the dry unit weight.The compression coefficient increases with moisture content,while decreases together with the increasing of the dry unit weight.Cuts modulus reduces when moisture content goes up,certain as moisture content is, it is going to magnify along with the increasing of dry unit weight,when both dry unit weight and moisture content are constant,cuts modulus will increase with the pressure.In certain dry unit weight conditions, the resilience modulus decreases as the moisture content increases,by contrast in certain moisture content conditions,the resilience modulus increases with the increasing of the dry unit weight.
