察尔汉盐湖是氯化物型的千盐湖。其中将有铁路南北贯穿,以岩盐为主的易溶盐类堆积,形成一种特殊的路基基底。盐湖岩盐的物理力学性质及路基的稳定性,成为多年来众所关心的一个问题。察尔汉盐湖岩盐地层是第四纪晚更新世和全新世的产物,地质年代新,盐层埋藏浅(上层最深23.5米,沿线最深17.7米)未经长期的地质成岩作用,颗粒之间互相连结较弱,不同于一般坚硬的沉积岩;化学沉积,
Chalham Salt Lake is a chloride type of the Salt Lake. Among them, there will be a north-south railroad running through and salt-dominated soluble salts accumulate to form a special subgrade base. The physical and mechanical properties of salt rock salts and the stability of roadbed become a matter of great concern for many years. Salt Lake Salt Lake in Qarhan Salt Quarry is a product of Quaternary Pleistocene and Holocene. Since the geologic age was new, the shallow salt burial depth (23.5 meters at the deepest level and 17.7 meters at the deepest level) did not cause long-term geological diagenesis. Weak link, different from the general hard sedimentary rocks; chemical deposition,
