| 摘 要： | 为了提高填石路基的强度和稳定度,避免不均匀变形对路基的不利影响,应用表面沉降法,研究了填石路基沉降率、密度、空隙率之间的关系。发现对于填石路基,上路堤单层摊铺厚度应控制在40 cm以内,沉降率应不超过3%：下路堤单层摊铺厚度应控制在60 cm以内,沉降率应控制在3%～5%之间。结果表明：以沉降率为指标的路基压实标准能够有效控制填石路基的压实质量。

| Abstract: | In order to enhance the strength and stability of subgrade and avoid adverse effect of the uneven deformation on subgrade,the relationship among settlement ratio,density and void ratio of rock-filled subgrade was studied by the method of surface settlement.It is found out that for rock-filled subgrades with thickness less than 40 cm,the settlement ratio should be within 3%;for those with thickness less than 60 cm,the settlement ratio should be between 3%and 5%.The results indicate that the standard of subgr... |
