The Analysis of the Impact of Liquid Limit on Mechanical Properties of Clayey Soil

Abstract

This article introduces the importance of the liquid limit of soil. The liquid limit largely determines the plasticity index and liquidity index of soil, which directly affects the classification and denomination of the soil. It also makes an analysis of the impact of liquid limit on the state of clayey soil and its mechanical indicators. Even if the water content is high and the porosity is large, as long as the water content does not exceed the liquid limit, it cannot be named silt soil. Under the same conditions, the higher the liquid limit, the harder the state of the soil, the higher the undrained strength and bearing capacity, and the smaller the coefficient of consolidation, but the liquid limit has less impact on the compression coefficient and compression modulus.
