摘要
镇江市第四纪沉积地层较连续,中上更新统下蜀组分布广,经古冲沟的切蚀及地表水的冲刷,多呈丘陵阶地。全新统分布于长江漫滩及几条主要冲沟之中。市区由于受人为活动的影响,普遍堆积有2～7m 的杂填土。国民经济日益发展,城市改造步伐在加快,高层建筑大量兴建,研究镇江市工程地质条件显得尤为重要。笔者根据工作实践,对镇江古冲沟与建筑工程的关系作一初步探讨。
The Quaternary system in Zhenjiang,mostly distributed in hills and terraces,is well-deve- loped.It has been cut by ancient gully and eroded by land sur(?)ace water.It is very important to study the engineering geological conditions for municipal construction. The ancient gully in the urban and suburban of Zhenjiang from the east to the west are: Jianbi gully,Dantu gully,Urban gully and Qilidian gully and all of them are extented to the Yangtze River.There are many middle and small ancient gully extented to large gully or direc tly extented to the Yangtze River which constitute branch-like ancient gully system.
