地下建筑:储存的特殊技术

摘要：
在过去的10年里，地下建筑在世界范围内的大城市里持续地稳定增加。造成这种情况的原因有很多。地表空间的缺乏和地表空间的昂贵是诸多原因中的一种。在希腊首都雅典，人口密度已经达到了8000人/平方公里，并且有限的空间中还充斥着极多的商业和工业场所。供需矛盾的日渐突出使得城市规划者尝试用各种办法来解决这个问题，这其中就包括地下空间的应用。最近，针对地下空间应用的实用性和可行性的调查已经在希腊展开，而这篇文章主要介绍的就是这项调查工程。地下储存仓库建设分为2个部分，第一是用矿山法修建地下空间，第二是在开发出的空间里修建出漂亮的，就像地面那样的储存仓库。虽然这两个部分有不同的特征，但是他们可以同时进行，并且第二步占用第一步所开发出来的空间。就像采矿一样，在地下空间开挖，有两个过程，先是钻孔，然后放炸药引爆。修建地下建筑大约需要两年时间。当它完成后，就能用做商业的储存结构了。(优秀毕业设计:www.2bysj.cn)

TECHNIQUES FOR A STORAGE FACILITY
ABSTRACT
Underground construction in metropolitan cities around the world has been steadily gaining ground during the last decades. This is due to a series of reasons, among them the lack of sufficient surface space and the increased cost of surface land. Athens, the capital of Greece, with a population density of 8,000 inhabitants/km2 and with the vast majority of the country’s commercial, industrial, and business activities gathered within its boundaries, is not an exception to these cities. One of the business sectors
that suffer from the scarcity of surface space is that of warehousing and logistics. The demand for new storage facilities increases, whereas the capacity of surface areas to host them is already exceeded. Urban planners tend towards innovative solutions that will alleviate the problem. Subsurface space utilization is regarded as one of them. Within this frame, a research project was recently carried out in order to examine the feasibility of an underground warehouse in the area of Athens. In this paper the engineering construction and management issues of the project are discussed. The construction of the warehouse is divided in two phases. First, the underground space is created using mining techniques. Second, the already excavated space is converted into a state-of-the-art facility, following the standards of typical surface warehouses. Although the two phases have different characteristics, they are planned to advance in parallel, with the second one occupying the areas already mined out. The room and pillar method is adapted from mining for the space development. Excavation takes place in two stages, using the drill and blast technique. Construction is anticipated to last about two years. At the end of this period, the space will be ready for commercial use.
