Lateral restraining and reinforcing structure for stabilizing high-fill embankment with soft oil foundation built on bed rock

Abstract

A lateral restraining and reinforcing structure for stabilizing a high-fill embankment with a soft oil foundation built on a bed rock is used for the lateral restraining and reinforcing of the foundation of the embankment in a region which is limited in the construction of a dug pile. The stability problem of the high-fill embankment and the construction difficulty of the dug pile are overcome, and the problems of insufficient horizontal bearing capability and large deformation of the traditional cast-in-situ bored piles are improved. The structure comprises left reinforced concrete cast-in-situ bored piles and right reinforced concrete cast-in-situ bored piles, which are symmetrically arranged at slope toes at the two sides of the embankment in the longitudinal direction at an interval, left reinforced concrete top beams and right reinforced concrete top beams, which are fixedly connected with the left reinforced concrete cast-in-situ bored piles and the right reinforced concrete cast-in-situ bored piles into a whole are respectively arranged at the tops of the piles, and anchor cables of which the two ends are connected with the top beams in an anchoring way are arranged between the left reinforced concrete top beams and the right reinforced concrete top beams in the extension direction of the embankment at an interval.

Description

technical field [0001] The invention relates to geotechnical engineering, in particular to a stable lateral restraint reinforcement structure for a high embankment covered with soft ground on bedrock. Background technique [0002] A large number of high-grade railways and highways have been built in China. In the course of the great development of road construction, a large number of soft soil foundation filling projects have been encountered, and there are a considerable number of soft soil foundation high filling projects. In many cases, the soft soil foundation alone The use of composite foundation reinforcement cannot satisfy the stability of the filling project on the soft soil foundation. For example, when the soft soil is overlying the bedrock, since the composite foundation measures cannot enter the bedrock, high filling projects will occur along the bedrock surface. Broken-line sliding failure, at this time, in order to ensure the stability of the high fill on the s...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a high embankment stability lateral restraint reinforcement structure with soft soil foundation overlying the bedrock, which is applied to the lateral restraint reinforcement of embankment foundation in areas where excavation piles are limited, so as to overcome the high embankment stability and the difficulty of excavation. Solve the construction problems of bored piles, and improve the problems of insufficient horizontal bearing capacity and large deformation of traditional bored piles
