Abstract
Aiming at the loess slope foundation, focused on three factors, which are the slope angle, the foundation depth and the slope distance, we have carried out a series of research experiments on the influence of the additional stress of the slope foundation.The test results show that the slope angle has great influence on the additional stress of the slope foundation.The bigger the slope, the greater difference between measured value and Boussinesq solution on additional stress of loess slope foundation, which proves that Boussinesq solution can not be directly used for the calculation of slope foundation's additional stress, it should be given the corresponding reduction;Tests in small slope distance, large slope angle and different foundation depth show that the increase of foundation depth has nothing to do with the improvement of safety on small slope length foundation and small angle foundation;Series tests on the slope distance show that the smaller the slope distance is, the more asymmetric additional stress appears in the soil beneath the foundation, and with the increase of slope distance, the asymmetry of the additional stress relieved.In order to choose the basis of the foundation on condition that it is not too conservative, at the same time meets the safety and stability requirements, we should choose the best slope distance.关键词
