新生代半成岩工程特性分析及工程岩体分级方法
摘要:在分析和总结新生代半成岩地质特征与工程特性的基础上，通过应用现行各相关规范中的工程岩体分级方法对新生代半成岩进行了基本分级评价，发现目前各相关规范中的工程岩体分级方法对大部分工程岩体具有较强的普适性，然而对于新生代半成岩这种介于"岩"与"土"之间的过渡型特殊介质适用性不强，评价结果难以突显新生代半成岩对工程建设影响的工程特性。进一步依据工程地质学理论分析与评价了现行规范中各工程岩体分级方法对新生代半成岩的适用性，并在总结前人研究软岩与新生代半成岩工程特性及分类的基础上，探讨性地提出了新生代半成岩的工程岩体分级评价思路及建议。
Abstract:Basic classifications and evaluations of the Cenozoic semi-diagenetic rock masses are carried out by using the engineering rock mass classification methods in the current codes, on the basis of analyzing and summarizing the geological and engineering characteristics of the Cenozoic semi-diagenetic rock masses. It is found that the engineering rock mass classification methods in the current codes have strong universality for most engineering rock masses, but the applicability for the special medium between "rock" and "soil" is not universal. It is difficult to highlight the engineering characteristics on the influence of the engineering construction. According to the theory of engineering geology, the applicability of the engineering rock mass classification methods in the current codes to the Cenozoic semi-diagenetic rock masses are further analyzed and evalerated. On the basis of summarizing the previous research on the engineering characteristics and classification of the soft rocks as well as the Cenozoic semi-diagenetic rock masses, the idea and suggestion of engineering rock mass classification evaluation of the Cenozoic semi-diagenetic rock masses is put forward.
