一、膨胀土的分布及主要地质特征在澳大利亚膨胀土分布较广,这类土当地亦称“反应性土”(Reactive Clays)。主要见于:绵亘于东海岸的沿海山脉的内侧,即昆士兰州和新南威尔士州内地;东南岸的维多利亚州境内,特别是墨尔本市以西,以及南澳大利亚州,其首府阿德雷得市的膨胀土已为愈来愈多的研究者所注意。在这些膨胀土中,胀缩性严重者当地称为黑土(Black Soil)——昆士兰州和新南威尔士州,或黑壤(Black earth)——阿德雷得
First, the distribution of expansive soil and the main geological characteristics of expansive soil in Australia is widely distributed, this type of soil is also known as “reactive soil” (Reactive Clays). Mainly found in: Mianyu lies on the inner side of the coastal mountains on the east coast, that is, in the interior of Queensland and New South Wales; on the southeast coast of Victoria, especially west of Melbourne, and South Australia, the capital of Adelaide, the capital of South Australia Soil has been paid more and more attention by researchers. In these expansive soils, the serious swell and shrinkage is locally known as Black Soil - Queensland and New South Wales, or Black Earth - Adelaide.
