China's housing fortification is less safe than decoration

BEIJING, May 18 (Lio The) this morning, the Chinese Academy of Engineering, Mr. Zhou Fulin in Guangdong Science Museum, a lecture called "Seismic fortification and Urban safety" science lectures.　　In the lecture, Zhou Academician explained the earthquake fortification situation in Guangzhou, and stressed that the construction of housing involves the safety of life and property, and he wants people to change their ideas and pay attention to the safety of houses. Zhou Academician analysis, China's housing fortification intensity is low, and is scheduled in 1969, is not allowed, has lagged behind. Most catastrophic earthquakes occur in low intensity areas, and houses collapse.　　Every big earthquake, whether it is the Wenchuan earthquake, or the Yushu earthquake, casualties are very heavy, most of the deaths are caused by the collapse of the house. The Chinese in the new century should change their ideas. There are a lot of uncertain factors in earthquake prediction, so we should take prevention as a precaution. Housing construction is related to our life and property security, should not be neglected. House structure Safety first, safety and decoration. "Zhou Academician said:" Whether in the countryside or the city, I often listen to people say that built a new house, spent 100,000 yuan on the decoration, and some people also asked the professional design, spending a lot. "Zhou Academician said:" I asked the people in Chengdu, in the decoration, they mostly spend the price of 1000-3000 yuan per square metre. Guangzhou people decorate to spend how much money, I now do not investigate, but certainly higher than Chengdu, so the emphasis on decoration ignore the concept of security should be changed. Beauty should be based on security, no security, no more beautiful. In fact, it is not too difficult to improve the safety of the house. Build a soft layer under the house, softness, this can make the safety of the house increase 3-4 times, and the cost is low, only 200 yuan per square metre. "Zhou Academician introduced, China is a frequent occurrence of earthquake disasters in the region, Guangzhou geographical location, in the coastal, in the moderate intensity zone, the current housing fortification intensity of 7 degrees."　　Guangzhou economy developed, the population is numerous, the house is dense, once the earthquake, the consequence is unimaginable. In the interactive session, a listener asked about Guangzhou's current viaduct and the safety of high road construction. Zhou Academician replied: "These bridges and high road building according to the traditional method of design, and did not use seismic and vibration isolation combined with the design method, although there are pads, but that is used to resist temperature, not for seismic, if more than 7 degrees, it is dangerous." "It is reported that Guangzhou will invest 150 billion yuan in the next 5 years to build 9 new subway."　　Questions have been raised by listeners about whether the construction of the subway will affect safety. Zhou said: "The subway itself has seismic design, so the safety under the subway can be guaranteed." The main influence of the subway is the people living along the line, they complained that the subway passed when there is a clear sense of vibration, fear in case of earthquakes or even minor earthquakes will endanger their safety. This requires the relevant departments to solve, if combined with seismic and vibration isolation method design, which can play a dual-protection role. ”
