設(shè)計(jì)條件本建筑為襄樊市市區(qū)一小區(qū)住宅樓。采用鋼筋混凝土全現(xiàn)澆框架結(jié)構(gòu)，建筑面積3000 m2，占地面積 m2 。 共六層樓，底層層高 。本。擬建場(chǎng)地為池塘經(jīng)人工填筑而成，地形平坦，場(chǎng)地分層情況如下：第1層為雜填土。 第2層為灰色粘土，厚8m。第3層為褐色粉質(zhì)粘土(未揭穿)。擬建場(chǎng)地范圍內(nèi)，淺部填土為上層滯水，主要受大氣降水及地表排水影響，—。承壓孔隙含水層。地下水對(duì)混凝土無(wú)侵蝕性。 氣象條件摘要主導(dǎo)風(fēng)向：東北風(fēng)基本風(fēng)壓： W 0=基本雪壓： S 0=0KN/m2
