在工业和民用建筑中,膨胀土给建筑物带来的危害在近年来已逐渐为人所知。据美国统计,该国每年损失达20亿美元之多,已将其作为“危害性环境介质”对待。 我国幅员广大,已知有14个省、自治区发现了膨胀土,遍及华北、西北、华东、中南、西南等行政区。 广西膨胀土分布相当广泛,且已造成了地张口、房开裂、公路移位甚至房屋倒塌等事

In industrial and civil buildings, the hazards that expansive soil has brought to buildings have gradually become known in recent years. According to U.S. statistics, the country loses as much as 2 billion U.S. dollars every year and has treated it as a “harmful environmental medium.” China has a vast territory. It is known that 14 provinces and autonomous regions have discovered expansive soils throughout the administrative regions of North China, Northwest China, East China, South China, and Southwest China. The expansive soil in Guangxi is widely distributed and has caused problems such as the opening of land, the cracking of houses, the displacement of roads, and the collapse of houses.
