CNN调查：委内瑞拉地震中倒塌的15栋公租房被指钢筋箍筋施工不合规、多处锈蚀严重
加拉加斯 — CNN 11月8日发布的一项调查分析显示，今年6月24日委内瑞拉发生7.2级与7.5级两次强震时，在沿海城镇 Caraballeda 倒塌的15栋政府公租房大楼，可能存在施工缺陷。
CNN 比对了这些大楼施工期间与倒塌后的影像后指出，在其中五个由总统府特别计划与项目办公室（OPPPE）负责建设的住宅区，钢筋箍筋的弯折角度看起来只有约90度，而委内瑞拉2006年建筑规范要求高层建筑的箍筋弯折135度；另有三个住宅区的影像显示金属支撑锈蚀严重，专家称这可能是混凝土质量不佳的迹象。卫星影像显示，Caraballeda 由该公租房机构建造的高层大楼中约63%在地震中倒塌。
结构工程师 Kit Miyamoto 等受访专家表示，这些缺陷可能使大楼在强震中更容易倒塌，但也提醒，在如此强烈的地震之后，很难证明某项缺陷与倒塌之间的直接因果。委内瑞拉政府在震后成立的委员会主席 Francisco Garcés 对 CNN 表示，委员会正对近100栋建筑取样分析。CNN 已向委内瑞拉政府与拉瓜伊拉州方面寻求回应，尚未收到回复。

CNN Investigation: Collapsed Venezuela Public Housing Towers Showed Improperly Bent Rebar and Deep Rust
CARACAS — An investigative analysis published by CNN on November 8 found that construction flaws may have contributed to the collapse of 15 government-built public housing towers in the coastal town of Caraballeda during the magnitude 7.2 and 7.5 earthquakes that struck Venezuela on June 24 this year.
Reviewing images and video from the buildings' construction and from after their collapse, CNN reported that at five housing complexes built under the Presidential Office of Special Plans and Projects (OPPPE), the short rebar ties known as stirrups appeared to have been bent to about 90 degrees, while Venezuela's 2006 building code required 135-degree bends in high-rise buildings across La Guaira. At three of the complexes, images also showed deep-seated rust in metal supports, which experts said could be a sign of poor-quality concrete. Satellite imagery shows that about 63 percent of the high-rise towers built by the special public housing authority in Caraballeda collapsed.
Structural engineer Kit Miyamoto and other experts who reviewed the evidence said the faults could have made the towers more prone to collapsing, while cautioning that a direct cause is difficult to prove after tremors of that strength. Francisco Garcés, president of the government commission set up after the quakes, told CNN that nearly 100 buildings are being analyzed with material samples and measurements. CNN said it had sought comment from the Venezuelan government and La Guaira officials and had not yet heard back.
