软土地区临河道路路面纵向开裂典型案例及原因分析

Typical Case and Cause Analysis of Longitudinal Pavement Cracking of Riverside Road in Soft Soil Area

温州的城市规划中,道路线位紧邻河道的情况比较普遍。由于温州地区大部分为软弱地基,力学性质差,因此在河道开挖或回填施工时需特别重视对相邻道路的影响。以温州某工业区临河道路路面开裂为典型案例,在事件回顾和资料收集的基础上,结合开裂路段路基工后沉降计算、裂缝出现位置、道路横坡变化等分析研究,提出道路路面开裂的原因和补救措施,为温州地区类似工程建设提供了参考和借鉴。

The situation of the road line adjacent to a river is quite common in the city planning of Wenzhou.Owing to the weak subgrade and poor mechanical property mostly in the area of Wenzhou, it is required topay more attention to the influence on the adjacent roads during the excavation or backfill construction of river. Taking the pavement cracking of riverside road in an industry area of Wenzhou as the typical case, and on the basis of accident review and the information collection, the article analyzes and studies the subgrade post-construction settlement calculation, crack position and road cross slope variation of the cracked road section, and puts forward the causes and remedial measures for the pavement cracking of road, which can be referred for the construction of the similar projects in Wenzhou.
