地下通道下穿水泥砼路面的沉降控制研究

Research into Subsidence Control for Underground Channel through the Cement Concrete Pavement

地下通道的施工将对路面产生一定的影响,施工期间需制定相应的沉降控制标准.应用结构力学和材料力学,推导出水泥砼路面沉降控制值的解析公式,并用有限元进行验证说明了该公式的正确性和适用性.该公式对同类工程制定沉降控制值具有参考价值.

The construction of underground channel has influences to the pavement.It＇s necessary to formulate the corresponding subsidence standards in the construction period.By applying structure mechanics and material mechanics,the subsidence control＇s analysis formula of cement concrete road surface is given.And through the finite element analysis,the accuracy of the formula is confirmed.This formula has the reference value for establishing the subsidence control for the similar project.
