Research On The Technology Of Risk Assessment Of The Bomb Shelter In The Transformation And Utilization

The content of this study is bomb shelter transformation and utilization of the technical risk evaluation.The content of this study is shelter transformation and utilization of the technical risk evaluation,Use relevant theoretical knowledge to analysis the shelter is in safe state to see whether there is use value.Why is this a research topic to the attention of the domestic scholar's,With the development of social economy,population increasing,leading to city to expand in the form of plane,and grow up in the form of three-dimensional,over time,the more space on the surface of the land can't satisfy the spatial sense of urgency of population explosion,the eyes of the people gradually turned to the underground space.For example:the subway,the subway development slows down the ground traffic congestion,is the preferred way to travel;Tunnel,but also facilitate the transport and travel Now people put eyes on the shelter is also the trend of the development of the society,through the transformation and utilization of war abandoned air-raid shelters will also became imminent.The study mainly used the theory of knowledge has general type unloading arch theory,the theory of rock pillars,sand theory and risk evaluation system.According to the shelter of the buried way to determine the bearing capacity calculation choose which kind of theoretical calculation.By calculating the results we can conclude abandoned shelter security status is whether meet the requirements,and will establish a system of technical risk evaluation system,eliminate risk measures to provide the basis for the next.At the same time,shelter in the transformation and utilization also have certain risk,such as casualties,ceiling collapse,water seepage,and so on dangerous condition,so we want to do a good job in risk assessment,avoid the happening of the risk.Engineering example of the main research of this article is on the foundation of the original shelter technology risk evaluation,through the security evaluation to develop a series of measures:such as reinforcement measures are taken to further transformation and utilization of back fill soil as foundation still continue to use is to study the contents of this paper.Therefore,after the technical risk analysis was carried out on the abandoned air-raid shelters and reworking and use is the inevitable trend of social and economic development,inherent important value and significance.
