摘要
湿软路基由于承载力较低,受力后路基变形大,施工中常常伴有路基不均匀沉降的现象,严重影响公路工程的验收质量。湿软路基不均匀沉降大,易导致公路路基开裂。鉴于此,从改善公路路基土的剪切性入手,采取有效措施,增强软土路基的强度和稳定性,最终减小此类路基的不均匀沉降。
Due to the low bearing capacity of saturated clay subgrade, the deformation of subgrade with stress is great, and the differential settlement of subgrade often appear during construction, which serious- ly affect the acceptance quality of highway engineering. The differential settlement of saturated clay sub- grade can result in the cracking of sugrade. Given this, starting with improving the shear resistance of sub- grade, effective measures are adopted to reinforce the strength and stability of saturated clay subgrade. Eventually, the differential settlement of subgrade will be reduced.
