High Filling And Deep Soft Foundation Of Culvert Structure Stress And Settlement Analysis

With the rapid development of China’s economy, infrastructure construction in our country vigorously construction, railway, highway, municipal construction, culvert engineering is applied more and more widely, high embankment and deep soft base set the culvert is widespread. In the past because of insufficient understanding of high embankment and deep soft base culvert, of structure design of force considered too large or too small. As a result, the engineering diseases; at the same time, the deep soft foundation of culvert foundation settlement analysis is not enough, resulting in culvert excessive settlement, eventually result in the destruction of the culvert. Therefore, research in the field of high embankment and deep soft base culvert was imminent, in the actual project has very important significance.This paper describes the compressibility of soil, and soil through the compression law analysis of high embankment settlement, this paper combines the stress analysis of past culvert, summarized the calculation methods of six kinds of vertical soil pressure on the culvert; at the same time through the culvert foundation stress calculation, expounds the analysis and calculation of high embankment and deep soft foundation of culvert force analysis, soil pressure of the culvert base, while the high fill culvert deep soft foundation for the mechanical behavior analysis; settlement analysis by soft ground under high fill; analyzed the law of settlement of high embankment culvert foundation deep soft foundation under conventional treatment methods; this paper summarizes the culvert soft foundation, puts forward the design principle of the line method and engineering application of uneven settlement of high embankment and deep soft foundation of culvert.
