海峡两岸主要岩体分类系统之比较探讨

Comparison of the Two Rock Mass Classification Systems Applied in Both Sides of Taiwan Strait

目前台湾隧道工程大都采用挪威Q系统与南非RMR系统进行岩体分类,当初引入时并未针对台湾地质特性加以修订,因此在应用过程中有许多未尽理想之处。就宏观角度而言,海峡两岸之地质条件较欧美地区类似,因此在岩体分类系统之应用经验方面较有相互参考价值。 本文探讨岩体分类系统于隧道工程所扮演之角色,并针对海峡两岸主要岩体分类系统之基本内涵加以概述,包括中国大陆制定之铁路隧道岩体分级系统、技术监督局与建设部所颁布之《工程岩体分级标准》,以及台湾地区现今常用之挪威Q系统与南非RMR系统,进而比较探讨各系统之适用范围及实用性,以供海峡两岸隧道工程界及台湾地区未来制定岩体分类系统之参考。

At present the Q and RMR classification systems which are developed by Norway and South Africa respectively are applied in most of the tunnel projects in Taiwan and no reversion is taken in view of the special geological character of Taiwan, therefore the result is not very satisfied. Generally speaking, the geological condition in Taiwan is more similar to that in Mainland than in Europe or America. Thus the experiences on rock classification gained in both sides can be taken as a reference by both sides. Moreover the basic contents of various rock classification system applied in both sides are described and compared in this paper, including rock classification for railway tunneling applied in Mainland,'Standard for Engineering' , A Q system from Norway and RMR from South Africa.
