【摘要】 通过对上海某冻结加固工程试验研究分析,提出了应针对上海地区软土矿物成分及水平渗透性强的特点,在开放系统中进行土体低温特性研究;同时就地下水的含盐量、土体冻结速率、土粒粒径、分散度等对土体低温特性的影响也提出了一些个人看法。更多还原

【Abstract】 The test of certain improvement construction in Shanghai by artificial ground freezing is analyzed. According to mineral composition andcharacters of powerful lateral permeability of sofl soil in Shanghai area. soi1 behaviors in lower temperature in opening system have be studied. Soil behav-lors in 1ower lemperature eaused by salt content of ground water, and freezing rate of ground, dimension of soi1 particles and dispersive degree are also dis-cussed.更多还原
