The ultimate principle of forming underground warehouse and concrete wall by the method of synchronous blast enlargement was expounded, and its characteristics was analyzed on the basis of experiments. 阐明了同步爆扩成型地下仓及混凝土仓壁的基本原理,通过对比实验分析了同步爆扩成型地下仓及混凝土仓壁的特性。
This paper studies the deforming characteristics of soil and the effect of concrete supporting in the course of synchronous forming of underground warehouse and concrete wall by experiments. 实验研究了集中装药同步成型地下仓及砼仓壁过程中土体变形特点和砼支护的效果。
The structure model selection of underground maintenance equipment warehouse has two characteristics : fuzziness and gray character. 地下维修器材库结构选型既存在模糊性,又存在灰色性。
When the relational degree or Hamming distance is equal, the superiority of the structural form can't be judged in case of using fuzzy sets and gray relational degree individually to the structure model selection of underground maintenance equipment warehouse with a few influencing factors. 单独用模糊集与灰色关联度的方法进行优选,对于影响因素较少的地下维修器材库结构选型,当关联度或海明距离相等时则无法判断结构型式的优劣。
In this paper, the characteristics and law of frost heave of artificially frozen soil and some factors that affect it are analyzed, aiming to do a better job in future construction of municipal infrastructure such as underground warehouse, and subway caves, etc. 在介绍人工冻结土体冻胀特性及阐述冻胀机理的基础上,分析了影响土体冻胀的诸多因素,以便更好的在市政工程中建设地下仓库(TUW)、地铁硐室以及进行深基坑支护等。
