发泡苯乙烯不仅广泛作为新鲜生食品的运输箱和电气产品等缓冲包装材料使用,而且在土木建筑领域作为隔热的建筑材料使用,大块的发泡材还可以代替道路的填土,用于处理软弱地基及轻量挡土墙。挪威15年前用泡沫苯乙烯施工的挡土墙至今完好。日本从1985年开始研究试用发泡材料作土工材料,曾在国道一号沼津绕越干道扩建工程中应用发泡材料处理软弱地基,取得了满意效果。
Styrofoam is widely used not only as a buffer packaging material for transportation boxes and electrical products of fresh raw foods, but also as a heat-insulating building material in the field of civil engineering, and bulk foaming materials can replace road filling In dealing with weak foundations and lightweight retaining walls. Retaining walls constructed with styrofoam 15 years ago in Norway are still intact. Since 1985, Japan has studied the use of foaming materials as geotechnical materials. In the first phase, National Road No. 1 Numazu has made use of foaming materials to deal with the weak foundation in the extension of trunk road and achieved satisfactory results.
