山区半挖半填路基差异沉降分析

ANALYSIS ON DIFFERENTIAL SETTLEMENT OF SUBGRADE HALF-CUT AND HALF-FILLED IN MOUNTAINOUS AREAS

针对山区半挖半填路基差异沉降问题开展研究,简述了山区半挖半填路基的研究现状和沉降机理,并对山区半填半挖类型的路基发生不均匀沉降的影响因素进行探究和分析,同时,结合某典型山区半挖半填路基案例建立理论模型剖析路基不均匀沉降的变化规律和发展趋势,重点从不同填方高度的角度分析其对半挖半填路基差异沉降的影响效应,为山区半挖半填路基工程提供重要的工程参考和指导价值。

This paper studies the differential settlement of semi-excavated and semi-filled subgrades in mountainous areas,briefly describes the research status and settlement mechanism of semi-excavated and semi-filled subgrades in mountainous areas,and explores and analyzes the influencing factors of the uneven settlement of semifilled and semi-excavated subgrades.At the same time,a theoretical model is established to analyze the variation law and development trend of uneven settlement of subgrade in combination with a typical case of semi-excavated and semi-filled subgrade in a typical mountainous area.Similar projects provide important engineering reference value.
