罗宁高速公路软基处理及沉降观测分析

由沿海高速公路的特殊地质情况 ,采用多种的软基处理措施 ,并对软基的沉降实施动态观测。根据观测的沉降资料 ,判断路基沉降的稳定性 ,并尝试由沉降曲线用双曲线函数推算软基的工后沉降量。

Various measures for weak subgrade treatment are used according to the special geological conditions for expressways along the seashore. Settlement of the weak subgrade is observed dynamically. Stability of subgrade settlement is determined in accordance with the observed data, and the settlement of the weak subgrade after completion of construction is tried to be predicated from settlement curves fitted by the hyperbolic functions.
