RESEARCH ON CHARACTERISTICS OF COHESIVE HYDRAULIC FILLS IN THE ADJUSTMENT ENGINEERING OF LEVEES AROUND EASTERN TAI LAKE
摘要
Abstract
The adjusted levee around Eastern Tai Lake is formed of cohesive hydraulic fills, which include lots of pebble-shaped clods. The paper conducts a preliminary research on the formation mechanism, internal structure characteristics and mechanical characteristics through field investigation,laboratory tests,etc. The results show that; the hydraulic fills are of uneven characteristics. The pebble-shaped clods are of good properties while the remoulded silt clay is of bad properties. The hydraulic fills are of small permeability and long consolidation time. The soil (est parameters do not conform with sites,the reason of which is that the prevailing soil test equipments are not suitable for the uneven fills. The parameters from in-situ tests can reflect the properties of the fills. The suitable ground treatment measures are water draining associated with heaped load or cement-soil mixing pile.关键词
