Abstract

Research purposes: With a large number of high － speed railways constructed in China，the environmental vibration induced by high － speed railway becomes prominent increasingly． The open trench has been widely used for the railway construction because of its easy construction and the relatively good isolation effects． In this paper，the numerical analysis is made to analyze the influence of the open trench ＇s depth and width as well as the load frequency on the isolation effect．

Research conclusions: The infinite element and visco － elastic boundary are used to simulate the semi － infinite space of soil condition，obtaining good effect． The calculation results indicate that the influence on the isolation effect is obvious when the depth of the open trench is in the range from 1m to 4m while the influence of the width of open trench produces a little influence． The isolation effects of the open trench on the near field is better than on the distant field． When the amplitude is fixed，the open trench has better isolation effect under the high － frequency load，and under the low －frequency load，the deeper open trench can have better isolation effect．

Key words
