Study On Bearing Capacity Of Foundation In Yushu Alluvial Silty Clay Layer

Bearing capacity of foundation is the premise of foundation design.Determine the bearing capacity and methods vary,but each method should follow accurate,simple principles of economic rationality.This paper introduces the development history of foundation bearing capacity of the relevant domestic and foreign,to determine the methods and research status,followed by a brief overview describes the geological features Yushu alluvial regions,while some stage more applications situ geotechnical testing methods,procedures and precautions are described.This paper focuses on the foundation bearing capacity and Yushu alluvial silty clay layer,in order to reflect the actual situation of carrying capacity elm alluvial soil of the shallow flat load test,static sounding situ testing and geotechnical routine testing data,and by the tip resistance,void ratio（e）and liquidity index（L_I）foundation bearing capacity(f_ak)and regression analysis,the establishment of a foundation suitable for Taiwan elm impact alluvial silty clay layer bearing capacity empirical formula.Finally,Yushu alluvial layer of silty clay（10）pile bearing stratum,foundation pile static load test,to determine the bearing capacity of the foundation pile characteristic values for the project area Yushu survey,designed to provide a useful information and reference.
