    "4 · 20" Sichuan Ya'an Lushan 7 earthquake caused huge losses, according to the county of Ya'an city county introduces, at present, the county water and electricity interruption, housing almost all damaged, including Wenchuan earthquake reconstruction of the building. (International Online April 21st)
    "Including after the Wenchuan earthquake reconstruction of building" almost all damaged, annoying. After the Wenchuan earthquake, reconstruction of buildings are in accordance with the "8 grade earthquake, seismic fortification intensity 9" requirements of the design and construction, to a magnitude of 8, seismic intensity of 9 degrees earthquake, building technology using frame structure, monolithic, the contractor has the construction level of qualification. The Ya'an earthquake, magnitude 7 magnitude, epicentral intensity of 9 degrees. According to common sense, after the Wenchuan earthquake reconstruction of the building should become the earthquake "boat of life", people should be high standards for the reconstruction of "prophetic vision" fortunate, however, does not belong to the epicenter of the Baoxing County, rebuilding was also not earthquake.
    Although the building in the earthquake will be damage, not simply on the basis of the seismic level and seismic intensity design, whether the design of the force size, angle and actual earthquake force size, angle fitted, is also a very important factor. But, back in the reconstruction of "responsibility be weightier than Mount Tai, the slightest who dare careless" oath, in accordance with the "8 grade earthquake, seismic fortification intensity 9" standard reconstruction of buildings, but almost all cannot resist the true magnitude of 7, which can not be questioned.
    In March 11, 2011, Japan had a magnitude of 9 earthquake, has triggered a tsunami, but the number of casualties caused by Japan, but only the 1/7 Wenchuan earthquake. Moreover, casualties are mainly the subsequent tsunami, rather than building collapse caused by. Anti-seismic requirements of Japanese architecture is 7, and after the Wenchuan earthquake reconstruction standard is "Building 8 grade earthquake, seismic fortification intensity 9," why our high standards as low standard in Japan? What are the criteria and Japanese don't butt, or we don't have Japanese seriously?
    Comparative study of scholars confirmed, the standard is a problem. In life, generally by 100 years of design, but our country according to the general 50 years or 70 years design; in the building structure type, Japan more than 60% adopts steel structure, our country about 90% of reinforced concrete structure; in the unit building area of steel consumption of unit building area, Japan Steel 90 kilograms, while China is only 60 kilograms; in the reinforcement strength, Japan the main reinforcement of 690 millions of Pascal, auxiliary reinforcement for 390 millions of Pascal, but our country is respectively 460 and 235 millions of millions of Pascal Pascal. Visible, the lesson of blood based on, we should modify the corresponding design code of building, to those standards.
    At the same time, also do need to acknowledge that, we do not have the Japanese seriously. After the earthquake and tsunami in Japan, the government completed the reconstruction of the target is 10 years, building reconstruction has not yet completed. A common eight or nine story building, only the aseismatic report often up to two hundred or three hundred pages, files and our high-rise buildings all, may be less than two hundred or three hundred pages; Japan is the real edge construction supervision, intermediate stoppage is commonplace, but our supervision almost useless; Japanese building inspection after the completion of at least two or three months, and we quickly a few days can handle.
    Every disaster, are worthy of our reflection; every contrast, let us all to find the reference and enlightenment. "8 grade earthquake, seismic fortification intensity 9" why cannot resist the earthquake of magnitude 7? We hope not to repeat such a heavy question mark.
    “4·20”四川雅安蘆山7級地震造成巨大損失,據(jù)雅安市寶興縣縣長介紹,目前,全縣水電氣中斷,房屋幾乎全部受損,包括汶川地震后重建的建筑。(國際在線4月21日)
    “包括汶川地震后重建的建筑”幾乎全部受損,令人惱火。汶川地震之后,重建建筑都是按照“8級抗震、9度設(shè)防”的要求設(shè)計施工,能夠抗震級為8級、烈度為9度的地震,采用框架結(jié)構(gòu)、整體澆灌的技術(shù)建設(shè),承建單位都具有建筑施工一級資質(zhì)。此次雅安地震,震級為7級、震中烈度在9度左右。按照常理,汶川地震后重建的建筑理應(yīng)成為這次地震的“生命之舟”,人們應(yīng)該為重建“先見之明”的高標準而慶幸,可是,不屬于震中的寶興縣,重建建筑居然也不抗震。
    雖然建筑物在地震中是否會被損害,不能簡單依據(jù)設(shè)計時的抗震級別和抗震烈度,設(shè)計時的受力大小、角度與實際地震中的受力大小、角度是否吻合,也是一個很重要的因素。但是,回想當年重建人員“責任重于泰山,半點不敢馬虎”的誓言,按照“8級抗震、9度設(shè)防”標準重建的建筑物,卻幾乎全部抵不住7級真震,這就不能不令人質(zhì)疑了。
    2011年3月11日,日本發(fā)生了強度為里氏9.0級的地震,還引發(fā)了大海嘯,但日本造成的人員傷亡數(shù)量,卻只有汶川地震的七分之一。而且,人員傷亡主要是后續(xù)海嘯,而非建筑物倒塌造成的。日本建筑的抗震要求是7級,而汶川地震后重建建筑的標準卻是“8級抗震、9度設(shè)防”,為何我們的高標準還不如日本的低標準呢?究竟是我們的標準和日本不對接,還是我們沒有日本人認真?
    學(xué)者的對比研究證實,標準確實是一個問題。在使用年限上,日本普遍按100年設(shè)計的,而我國普遍按50年或70年設(shè)計;在建筑結(jié)構(gòu)型式上,日本60%以上采用鋼結(jié)構(gòu),我國約90%采用鋼筋混凝土結(jié)構(gòu);在單位建筑面積用鋼量上,日本單位建筑面積用鋼筋90千克左右,而我國只有60千克左右;在受力鋼筋的強度上,日本主力受力鋼筋為690百萬帕斯卡,輔助鋼筋為390百萬帕斯卡,而我國分別是460百萬帕斯卡和235百萬帕斯卡??梢?,基于血的教訓(xùn),我們應(yīng)該修改相應(yīng)建筑設(shè)計規(guī)范,向高標準看齊。
    同時,也確實需要承認,我們做事沒有日本認真。日本地震海嘯之后,政府完成重建的目標是10年,建筑重建至今還沒有完成。普通的一個八九層公寓樓,僅僅其抗震報告書動輒厚達兩三百頁,而我們一棟高層建筑所有的文件,可能還不到兩三百頁;日本是真正的邊建設(shè)邊監(jiān)理,中間停工是常事,而我們的監(jiān)理幾乎形同虛設(shè);日本一棟建筑完工后的檢驗至少也得兩三個月,而我們最快幾天就可以搞定。
    每一次災(zāi)害,都值得我們反思;每一次對比,都讓我們?nèi)ふ医梃b和啟示?!?級抗震、9度設(shè)防”為什么抵不住7級地震?希望我們不再重復(fù)這樣沉重的問號。
