我国沿海地区，广泛分布着性质极为软弱的近代沉积的欠固结软土。
The unconsolidated marine soft soil has very weak engineering geological properties which is widely distributed in the coast area of China.
软土是指以水下沉积的软弱粘性土或淤泥为主的地层，有时也夹有少量的腐泥或泥炭层。
The soft soil refers to the soft clay deposited under water or mud-based formation, sometimes with a small amount of rot folder mud or peat layer.
主要的工程地质问题有：软土、粉土、膨胀土（岩）、滑坡、崩塌岩堆、岩溶、破碎软弱岩体等。
The main engineering geological problems are as follows:soft soil, powder soil, welled soil (rock) , landslip, breakdown talus and broken weak rock mass.
