Disaster prevention and reduction needs too " Soft to set up defences"
Staff reporter Wang XueFei On June 24, the Chinese Technology Association hosted " symposium of taking precautions against natural calamities of natural disasters relief " in the Great Hall of the People . The experts from fields such as earthquake, architecture, climate, prevention from suffering from the diseases, electricity,etc. point out in the report, disaster prevention and reduction, not merely need to strengthen the calamity to monitor, it is " hard " to strengthen house, road, water, electricity and gas engineering construction,etc. Means,last " set up defences softly " ,Strengthen the ideology of disaster prevention and reduction, strengthen relevant standardard management and system mechanism to reform. The epidemic situation is prevented and controlled and can't be relaxed a few days ago, Center for Disease Prevention and Control of China (CDC) The chief scientist of epidemiology has only made a field survey in Mianyang, Sichuan, heavy calamity countied District of 5 earthquakes of Deyang. He says, since the heavy earthquake of Wen Sichuan took place, up till now, Wen Sichuan earthquake-stricken area has not really had great infectious disease epidemic situationed that take place, but still can't relax the prevention and control of the epidemic situation. For example after earthquake, California of U.S.A., take place 1989, break out and prevail after presenting the sporular fungus of ball. Water, Ganges River of India, overflow 1991, take place earthquake in the same year, take place two year the intersection of lung and plague break out prevailing. In 2006 and 2008, earthquake and the prevalence of measles and malaria breaks out will take place on the volcano and erupt in Philippine and Costa Rica. Zeng Guang says, in 1998, when the heavy floods take place in the Changjiang River, Song Hua River, Nenjiang basin, China CDC has proposed " There is no great epidemic disease after the great calamity " Standard. First, the number of people dying of infectious disease after the calamity should be far lower than because the number of people of the calamity death directly. Second, there are not great infectious disease especially prevalence of strong infectious disease. Third, do not have because infectious disease prevails and normal life and production of the disaster relief work influence people. These three standards are applicable too now. Have only thought, the epidemic situation of Wen Sichuan earthquake-stricken area prevents and controls and roughly divides 3 stages: Prevent and cure stage in infectious disease in summer and autumn, prevent and cure stage in the coming winter-spring period and resume stage in an all-round way. Prevent and cure stage in infectious disease that at summer and autumn at present, after it requires at least from 3 years to 5 years, there are no infectious disease and important public health event to happen, spends safely these 3 stages. Hospital school should raise, set up defences the intersection of grade and the intersection of Wen and middle and primary schools personnel that Sichuan lead to the fact by loud earthquake suffer heavy losses, make common people shocked. Ou, Vice President of Architectural Society of China and president of institute of technology of Dalian enters the duckweed academician to think, with the prominent improvement of comprehensive national strength and economic strength, cities and towns and rural earthquake disaster of our country should change correspondingly to defend the countermeasure. For example use external experience, the grade or goal of setting up defences that the ones that improve the middle and primary schools, hospital and large-scale public buildings facility provide fortification against earthquakes for reference. It is introduced, the present common norm of architectural design of our country small shakes and does not shake badly, middle and can be repaired, great and shake and does not fall. Since 1974, the first overall antidetonation norm of our country had already been revised many times, was absorbing the new scientific technological achievement constantly, have offered legislative authority for building structural design and evaluating in the future. A question that the heavy earthquake exposes in this Wen Sichuan is, the building (including the school, hospital) collapsing Quite a few have not carried on aseismatic design, can not reach the requirement of essential structure. Some buildings lack basic general knowledge, such as the reinforcing bar does not place on receiving the strength area, but while placing on, roof and wall lack reliable connection,etc.. American-European countries put forward the clear requirement to buildings such as the school,etc. - -Improve the antidetonation grades of 20%~33% than the ordinary commercial building, but our country does not have this kind of standard. The expert proposes: Confirm the standards of setting up defences of the middle and primary schools, hospital and large-scale communal facilities as soon as possible, provide the standard of setting up defences or goal of setting up defences.
