During the process of the fore mentioned analyses, some tentative works as follows were done.(1)On the basis of the fundamental of spatial analytic geometry, the basic method for displaceable block searching was put forward and the relevant program was written. With this program one can easily search out all the displaceable blocks and omitting of blocks, which is very common in searching blocks manually, can be avoided.(2)The coefficient of stability of blocks with failure mode II-2(that is, sliding on a single sliding surface, but confined by near intersecting line )was deduced.(3)The multi-cavern effect of Laxiwa underground caverns was studied on the assumption that all of the caverns were full face tunneled at the same time.(4)The stability classification scheme of rock mass surrounding large scale underground caverns was established. In addition to inherit the merits of the method of engineering geological

在完成上述工作的过程中，本论文主要在以下几个方面进行了一些探索：①基于空间解析几何原理，提出了块体搜索的基本思路并编制出相应的程序，基本实现了块体搜索的自动化，既大大缩短了块体搜索时间，又能防止因人工搜索引起的遗漏；②推导出Ⅱ-2型(单滑面滑动，但受侧限面约束)块体的稳定性系数计算公式；③以数值模拟方法论证了拉西瓦地下厂房洞室群全断面一次开挖时群洞效应的具体特点；④以岩体质量、开挖效应、群洞效应和次生灾害效应为评价指标，建立了&大型地下洞室群围岩稳定性分类&方案；该方案既继承了水电行业规范&围岩工程地质分类&法的优点，又综合考虑了大型地下洞室群的工程特点。

ABSTRACT: On the basis of investigation and research, the paper analyzes the current situation and problems, suggests the structures and contents of emergency preplan, and furthermore, emphasizes the importance of training and drilling of the accident emergency preplan for urban underground public space.

在调研的基础上，分析了城市地下公共空间事故应急预案的现状及问题，提出了城市地下公共空间事故应急预案体系的结构层次及设计的内容，强调了城市地下公共空间事故应急预案的培训演练的重要性。

The present government wants to get rid of chaotic underground situation quickly for two reasons:(1) It is partially responsible for the creation of underground radio stations, these stations have become the liabilities which might come back to haunt it. Thus, changing media policy by legalizing them would be the plausible way of expunging that shadow.(2) By using market power to corner these underground stations is an ideal strategy to reform a monster it once cherishes so dearly, this would further avoid these stations turning against it.

而民进党执政之后，基於以下两个理由也想尽速解决眼前这个混乱的状况（1）地下电台的兴起与新政府过去从事的反对运动有关，当在野党成为执政党，这些电台可能是潜在的反对力量，促使这些地下电台合法化可使执政党免於被伤害的忧虑；（2）利用市场力量边缘化地下电台是理想的策略，也可以避免这些电台再度形成反对势力。
