石灰在我国使用有着悠久的历史。由于生产石灰的原料分布极广,生产简单,使用方便,成本低廉,并具有良好的性能,因此长期以来,石灰一直是建筑工程中应用很广泛的气硬性胶凝材料。石灰桩在美国、日本、瑞典等国应用较多,尤其是日本,采用石灰桩加固地基,经过二十多年的试验和研究,积累了不少实践经验,并摸索出一套施工方法。我国从六十年代开始,就有人从事石灰桩加固软土地基的试验研究。到1975年,铁研院、交通部一公路局在天津采用石灰桩处理软土路基,
Lime has a long history of use in our country. Due to the wide distribution of raw materials for production of lime, simple production, convenient use, low cost, and good performance, lime has long been a widely used gas-hardening cementitious material in construction projects. Lime piles are widely used in the United States, Japan, Sweden, and other countries, especially in Japan. The foundation is reinforced with lime piles. After more than 20 years of experiments and researches, many practical experiences have been accumulated and a set of construction methods has been explored. In China since the 1960s, some people have been engaged in experimental research on the reinforcement of soft soil foundation with lime piles. By 1975, the iron and steel research institute and a road bureau of the Ministry of Communications used lime piles to treat soft soil roadbeds.
