摘要
随着我国加强经济欠发达地区的公路建设,进一步加大路网密度,加强区域间联系,在山区丘陵地带修建公路的比例大大提升,在山区的填石路基由于其取材方便、承载力高、后续沉降量小等特点被广泛采用。在京漠公路樟岭至西林吉A1标段的填石路基上,进行地基系数(K30)检测方法与动态变形模量(Evd)相关性分析,并在其中优选一种填石路基检测方法作为标准检测方法进行推广。
As China strengthens road construction in economically underdeveloped areas,further increases road network density and strengthens inter-regional connections,the proportion of roads built in hilly areas in mountainous areas has greatly increased.Stone-filled roadbeds in mountainous areas are easy to obtain and carry capacity the characteristics of high and low subsequent settlement are widely used. The proportion of stone-filled subgrades in the A1 section of the Zhangling-Xilinji section of the BeijingMountain Highway is as high as 42%. Strengthening the testing of stone-filled roadbeds will help improve the quality of the filling.Correlation analysis between the detection method of the foundation coefficient K30 and the dynamic deformation modulus( Evd) is performed on the stone-filled roadbed,and the most suitable detection method of the stone-filled roadbed is selected among them.
