摘要
通过对铁路土质边坡上不同土质、不同地形、不同入土深度、不同材质(钢或木)的128根打入桩的水平静载试验研究,得到不同条件下各种长度钢、木抗滑桩所能承受的水平力,为土质边坡滑坍抢修时如何选择适当长度、排数的钢桩或木桩提供参考。试验结果表明,边坡上抗滑桩的水平极限承载力与坡脚平地上抗滑桩的水平极限承载力相比,并没有规律性地减少,水平值相差不大;在均匀土层中,不同桩型、不同土质抗滑桩的水平极限承载力与其埋深基本成正比线性关系。
Based on the test and research on horizontal static load of 128 driven piles made of different materials (steel or wood) and driven in various soils and landform in different driving depth, the horizontal forces of steel and wood antislide piles with different length and conditions are obtained. It provides the references for selecting proper length and number of rows of steel and/or wood pile in rescuerepairing of collapsed subgrade slope on railway line. The test results show that the horizontal limited bearing force of antislide piles driven in soil slope has no disciplinary reduction and big difference in horizontal value compared with the ones driven in slope heel, and, the horizontal limited bearing force of antislide piles driven in various soils is linearly proportional to the driving depth.
