Numerical Analysis and Reinforcement Study of a Roadside Slope in Xinjiang

Abstract

Road construction excavation on a road side slope stability constitutes a serious impact, in order to ensure the stability of the slope, the construction of finite element model analyzed the slope stress field, displacement field changes, determined that the slope stability coefficient of 1, does not meet the engineering requirements;Based on the numerical analysis and site investigation, two reinforcement schemes were determined: “Scheme 1: Anchor + Anti-slip Pile + Clearance; Scheme 2: Anchor + Anti-slip Pile + Interceptor Drainage”.The stability coefficient of the slope before reinforcement is increased by 38% in scheme 1, and 50% in scheme 2. Comprehensively comparing and analyzing the stress field and displacement field changes of the anchor and anti-slip piles as well as the stress field and displacement field of the slope body in the two schemes, and taking into consideration of the long-term stability of the slope and the economic cost, it is determined that scheme 1 is the final reinforcement scheme.
