沿街建筑应连通街道和内院的人行通道，其间距不宜超过( )。
A．150m
B．130m
C．100m
D．80m
参考答案：D
解析： 见《高层建筑设计防火规范》(GB 50045—95)(2005年版)第4.3.1条，高层建筑的周围，应设环形消防车道。当设环形车道有困难时，可沿高层建筑的两个长边设置消防车道，当建筑的沿街长度超过150m或总长度超过220m时，应在适中位置设置穿过建筑的消防车道。有封闭内院或天井的高层建筑沿街时，应设置连通街道和内院的人行通道(可利用楼梯间)，其距离不宜超过80m。
| Air France SA said Monday that its second-quarter net profit fell 35 percent to 57 million ($57.4 million), but sales were steady and operating profit surged. Earnings before interest and tax, a measure of operating income, gained 86 percent to 141 million as fuel costs fell and cargo traffic rose. Air France has been hurt less than rivals such as British Airways PLC and Lufthansa AG by the slowdown on North Atlantic routes following the war on Iraq in 2003 because it has fewer flights in that market. Net income fell as the airline paid deferred taxes that came due. Sales rose 0.9 percent to 3.2 billion. The carrier lost about 80 million in revenue because of a four-day strike by pilots in September. An accord was reached tying future pay increases to inflation. The carrier said that first-half fuel costs fell 15 percent to 680 million. Cargo traffic rose 11 percent in the second quarter, while passenger traffic rose 1.1 percent. The airline’ s shares gained 87 cents, or 7.7 percent, to close at 12.11. Separately, Air France and Alitalia SpA agreed to buy 2 percent stakes in each other as Europe’s second-and sixth-largest airlines deepen their partnership. |
