斜向旋喷桩加固 既有重载铁路路基状态评估
Evaluation of subgrade condition of existing heavy haul railway by oblique jet grouting pile
摘要
Abstract
In this paper, the heavy haul railway subgrade of Shuo Huang was taken as an engineering example, which was reinforced by the inclined rotary jet grouting pile. Through the field test of typical subgrade section, the subgrade condition before and after reinforcement was evaluated. The stability of the subgrade of the corresponding section was analyzed and calculated, and the stability safety factor was obtained before and after the reinforcement. With the aid of the finite element software, the plane model was established, and the settlement of the subgrade surface under the action of the train load was evaluated. The reinforcement effect of inclined rotary jet grouting pile was comprehensively analyzed. The results show that the oblique jet grouting pile has an active effect on improving the stability of subgrade and reducing the settlement of subgrade surface, which can be referred by similar projects.关键词
