Analysis of soil arching effect with different cross-section antislide pile

Although the knowledge of soil-arching effect of anti-slide pile become common, the analysis of soil-arching\ud effect with different cross-section anti-slide pile is little. Therefore，this paper choose three typical crosssection\ud piles (rectangular, square, circular), Then do some study about the Mechanism of mechanism, frictional\ud arch and end bearing arch of three cross-section piles and the form of soil arch with different cross-section and\ud the soil arch zone under same condition in order to define the best cross-section, The result show that\ud rectangular section pile and square section pile are composed by frictional arch and end bearing arch, while\ud circular section pile is made up by united arch, finally rectangular section pile has a more effective retaining\ud effect than square section pile and circular section pile through compared soil arch zone with three type section\ud piles.\ud Keyw
