吸取四川地震校舍垮塌的血泪教训

黄铁屿  吴莉/加州亚凯迪亚市CIEDM
2008年5月24日

 

这次汶川大地震反应出震区学校建筑的品质有致命的缺陷。有很多人问:“这些不经“震”的校舍,问题出在哪里?”本文的目的

就是以加州公立学校校舍建筑的设计施工规范要求为借鉴,做为中国政府改善学校建筑的参考。 

 

洛杉矶时报在5月14日与24日两次报道,此次汶川地震中多所学校因校舍建筑的品质低劣以致倒塌, 至少有上千名学生惨被压

死,伤者包含截肢求生者更是不计其数。 现在仍然有数以百计、甚至数以千计的学生被埋在瓦砾里,生死不明。该报道中也

指出,伤亡学生的家长们对有关政府官员已有明显的不满情绪与抗议动作。实际上,此次地震中学校伤亡惨重的问题,已

广泛地被中国网民提出并指责。 


CIEDM进行了调研总结, 据至5月14日截止的报道,汶川木鱼镇中学的一幢三层宿舍楼倒塌,造成400名学生伤亡,含90多

名学生遇难,191名学生失踪,120余名学生受伤;四川绵竹市汉旺镇,一所中学和一所技校倒塌,两所学校至少有200人被

埋;德阳市下辖的什邡市里,5个乡镇的学校倒塌,被压300余人;北川县第一中学是老校区,共有学生2600多人,至今还

有1000名左右学生被压在废墟下。在这次地震中,尤以教育闻名的都江堰聚源中学损失让人揪心,两幢教学楼轰然倒塌,导

致240余名师生遇难,但是镇上的其它建筑却只是受到损害,并无垮塌。 据5月25日截止的统计,除汶川、北川等重灾区,四

川省校舍倒塌6898间。这些资料很明显地显示出这些校舍的确是“豆腐渣工程”。在这次灾难中,许多学生需要截肢保命,

终身失去了手臂或腿脚。


加州建筑法规在每次震灾后,都会有系统的检讨改进。在加州,根据建筑物的使用功能不同,其结构安全设计标准也有所不

同,基本上可分为一般建筑、关键服务建筑、及公立学校三大类。一般建筑指平常的一般住商工建筑物;关键服务建筑包括

医院、警察局、消防局及政府救灾处理通讯中心等,这些建筑物在地震发生后,仍需继续正常运作,以达到救灾的功能,因

而需符合较高标准的法规要求。


在公立学校校舍的建筑方面,同样也有较高的设计标准。在1933年南加州发生的长堤地震造成许多公立学校的建筑物倒塌,

为避免再度造成校舍损毁及教职工、学生的伤亡,加州政府针对公立幼儿园、小学、中学、以及社区学院校舍的兴建,在加

州建筑法规及其专章第24款,制定了更高要求的地震安全设计及施工规范,并由“州建筑师处”来负责审核监督公立学校的建

筑设计及施工,而非地方上专责教育的学区或县市政府单位。第24款中有许多严格的规定,譬如自1988年起要求申请人提出

详细资料供主管单位评估地震时可能导致地层位移、滑坡塌方、地表破裂等,并要求土壤报告书提出工程地质的结论,而且

地震位移设计得在建筑设计完成前审查完毕。正是因为这套制度的实施,使得加州后来发生的大地震,包括1994年的北岭地

震,公立学校新建校舍都无重大损伤。

 

综上所述, 加州学校建筑安全的制度有下列特色:(1)加州建筑法规针对公立学校辟有专章,定出较一般建筑更严格的方针

要求;(2)每次震灾后,加州地震安全委员会都会对建筑的安全规范做全盘检讨,经过各界论证后,再由加州建筑标准委

员会审核通过后形成新的法规;(3)建筑图纸的审核与施工的监督,由“州建筑师处”而不是地方政府来执行。 由此可见,

加州对于学校建筑从设计、审核到施工品质,面面俱到,层层把关,务求保证学校建筑的优等质量。为避免中国学校建筑在

重建过程中再度成为“豆腐渣”工程, 我们建议中国政府对于学校建筑应建立比一般建筑要求更高的安全设计规范,并成立专

责机构执行严格的监督管理。
