【摘要】 在纵横向填挖交界路基处会出现非均匀沉降现象 ,过大的非均匀沉降将引起路面结构的破坏。本文通过现场沉降观测、FWD弯沉检测证明 ,层铺土工格网可以有效地提高填土抵抗变形能力、改善路基沉降的非均匀性 ,不失为一种能有效地解决填挖交界路基非均匀沉降的方法更多还原

【Abstract】 It is usual that uneven settlement of subgrade occurs in the boundary area of cutting and filling,which may result in pavement structural damage This paper presents a stratified reinforcement treatment by using geo?grid to improve settlement resistant capability of the filling area,with field test experiment and measurement by FWD The treatment is proved effective in controlling uneven settlement of subgrade in the boundary area of cutting and filling更多还原
