本文系关于在地下水位上的,位于自垩士及含硅白垩土层建造的一个储存液化石油气的气密性的岩洞储存装置的地质的、水文的以及土力学方面的调查报告,同时并包括有工程设计及其施工方法。地质的必要条件为适当均匀;整体及具有延续构造的或为一岩石块体;水文的必要条件是保护岩洞避免污染淡水水源;土力学方面,则要求岩石构造必须具有以下特性,即宜于不用爆破方式的开挖和不用支撑但强度可达一经济许可的稳定的断面。一个287米长的岩洞以极为精确的允许偏差开挖而成,其气密性是以在浇注的混凝土衬砌岩墙上粘贴大张的塑料板从而得以保证。这种对小型的、运转用的液化石油气储存装置的新型研究可以很容易的应用于石油蒸馏及易燃液体的储存装置。
This paper is a survey of the geologic, hydrological, and soil mechanics of airtight cavern storage at groundwater level located in a Cretaceous and siliceous chalk-bearing formation that stores liquefied petroleum gas. At the same time, Including engineering design and construction methods. Necessary conditions of geology are properly uniform; the whole and continuous structure is a rock block; hydrology is necessary to protect caves from polluting freshwater sources; and in terms of soil mechanics, the rock structure is required to have the following characteristics Blasting methods of excavation and without the support but the strength of an economic permitting a stable cross-section. A 287-meter-long cave is excavated with extremely precise tolerances and its airtightness is ensured by the application of large sheets of plastic to the cast-in concrete lining rock walls. This new type of research into small, operating liquefied petroleum gas storage devices can easily be applied to petroleum distillation and storage of flammable liquids.
