简介:摘要为掌握铁路桥梁桥墩基础冲刷情况和桥址处河道变迁及河床冲刷、淤积情况,对桥径渡洪能力作出评估,同时为水文检算提供依据,我处对桥址处和桥轴线上、下游各25米位置,确定横断面分别进行测量。
简介:<正>汉水发源于陕西南部,经鄂西北流至湖北中部,在武汉市汇入长江,将长江北岸的市区划分为汉阳和汉口两大块。入口处界线清楚,清浊分明。汉水中游江水清清,两岸杨柳依依,农田平展,风景秀丽,是有名的稻棉产区。有谁能想到,在江汉平原上还曾经有古象生存呢?可就这里的汉水河床中却深埋着远古的象类遗骸。1983年4月上旬,某工程队在荆门县沙洋镇边的汉江上施工,挖掘河底时,潜水员在河床堆积中发现了古象化石。出土地点靠近汉江东岸,距现在岸边约110米。距水面的垂直深度约32米。河床上层为沙砾层,厚约12米。砾石磨圆度良好,砾径一般为3—5公分,最大不超过8公分;结构较松散。沙
