| Abstract: | It is discussed that horizontal foundation modulus is an important parameter in calculating the deformation of deep excavation project and evaluating the stability of the retaining structure.It also play an important role in calculating the displacement and the internal force of piles which is subject to horizontal load.In addition,due to technical limitation,horizontal foundation modulus is hard to determine.It is discussed the factors which affect this parameter.The measurement procedure of the horizontal foundation modulus and its influence on the outcome were presented.The results were obtained,which showed that the classification,mechanical properties,stress level and state,time effect of soil have fair influence on K_h. |
