| 摘 要： | 从公路工程的角度出发,研究中国极软岩石的分布及对公路建设的影响。以岩石的单轴抗压强度为标准对极软岩石进行定义,在归纳和总结极软岩石成因、分类、组成及工程力学特性的基础上,进一步介绍了中国极软岩石的分布状况。在分析、归纳中国极软岩石分布规律的基础上,从极软岩石对公路工程建设影响的严重程度出发,主要分析了极软岩石对公路路基和边坡工程两方面的影响。

| Abstract: | Froming the angle of the highway engineering,the distribution of extremely soft rock in China and its influences on highway construction are studied.The uniaxial compressive strength is used as the standard to define extremely soft rock.After summarizing the cause of formation,classification,composition and engineering mechanical characteristics of the extremely soft rock and the distribution of the extremely soft rock is further introduced.On the basis of the distribution rule and the serious degress of influences of the extremely soft rock on the construction of the highway engineering,the influences of the extremely soft rock on both sides of roadbed and side slope of highway are mainly analyzed. |

| Keywords: | extremely soft rock distribution highway construction influence |
