- 摘要:
- 目前采用振冲法加固软粘土地基经验还不多。为了验证在围垦的海涂地基上的应用效果进行了油罐底板。罐基边缘沉降;地基中孔隙水压力;地基侧向变形;罐基底面反力等现场测试工作。之后又在吹填土地基上的两个油罐工程中进行了振冲前后的含水量、静力触探、现场十字板和桩载荷试验等测试对比工作。实践证明,用振冲法加固软粘土地基,可提高地基承载力近1倍,加固后的复合地基最终沉降与天然地基相比减少三分之一左右。
At present, there are not many experiences in using method of vibration and impulse to con-solidate soft clay base. In order to verify the application effects in weired seabeach base, in-situ testing and measuring on setttlement of buttom plate and brim plate of oil tank, pore space water pressure in the base, sideway deformatoin and countee-force of the base was carried out. Also, in two oil tank protects with blowing-filling soil base, the measuring and contrasting on water con-tent, static force exploration, load bearing of in-situ cross plate and column were caried out before and after vibration and impulse. The above practice proves that using the method of vibration and impulse can increase the base bearing ability by one time and the final settlememnt of complex base after consolidation can reduce one third than that of nature base.1991,5(5): 1-7 收稿日期：1990-12-1作者简介：作者生于1937年，1962年毕业于哈尔滨工业大学土木系工业与民用建筑专业。一直从事石油化工土建工程设计工作。近20年来，先后在浙江、上海、天津等沿海软土地区负责进行了大型油罐地基试验研究工作，曾荣获部级科研成果二等奖两项、三等奖两项，并有两项列入国家科委重大科研成果公报。在国内外学术刊物上发表有关论文20多篇，编著有《大型油罐地基处理》。现任上海市土木工程学会岩土力学与地基基础工程学会地基处理委员会委员等职。高级工程师。参考文献：
