抗滑桩截面尺寸对土拱性状的影响
INFLUENCE OF SECTIONAL DIMENSION OF STABILIZING PILES ON SOIL ARCHING CHARACTERISTICS
摘要
Abstract
The stabilizing pile is widely used in the governance of the high slope.And the soil arch characters,including the soil arching type and the soil arching height,which may be affected by the sectional dimesion of the stabilizing pile,have an important role in the design of the stabilizing pile.This paper firstly adopts the numerical simulation technique to research the influence of the sectional dimesion to the soil arching characters,then this paper combines with the mechanical calculation to explain the reasons for changes of soil arching types and soil arching heights.The result shows that under the circumstance that the clear distance between piles is definite,along with the decrease of the pile sectional dimesion.The soil arching type is more likely to transfer from the end bearing arching to the friction arching.As for the end bearing arch,the soil arching height is mainly affected by the width and suffered pressure of the pile back.Along with the increase of the width of piles,the height of the soil arching increases.As for the friction arching,the soil arching height is mainly affected by the height and suffered pressure of the pile section.Along with the increase of the height of the pile section,the height of the soil arching increases accordingly.关键词
