A simplified method to predict creep behavior of the Yangtze River Sand
Abstract The paper reports a study into the creep behavior of Yangtze River sand, which has implications for both the sustainability and serviceability of structures and the prediction of land subsidence in this area. Following sieve analysis, sand was compressed under pressures of 800, 1,600 and 3,200 kPa, with sieve analysis repeated after each test. This indicated particle crushing. Samples were also compressed by 800 kPa for 0.5, 1, 10, and 100 min, which indicated particle breakage is associated with creep. A new method is proposed to calculate the creep strain of Yangtze River sand, especially where laboratory test results are not available. Two case histories are presented which demonstrate the validity of this simple method for the prediction of post-construction settlement of a high-rise building on Yangtze River Sand and subsidence related to a pumped aquifer.
