摘要
通过自然解冻和强制解冻原位试验,得出冻土自然解冻和强制解冻温度变化规律。冻土自然解冻速度非常缓慢,强制解冻能显著的加快冻土解冻速度。对于多排管冻结形成的大体积冻土,可利用强制解冻加快冻土解冻速度,达到及时跟踪注浆,更好的控制融沉目的。
Through the field experiments of natural thawing and artificial thawing,a conclusion is drawn that the natural thawing velocity is very slowly and the artificial thawing can accelerate the thawing velocity.For large volume frozen soil developed by multi-row freezing,it is a better choice to use artificial thawing method,so that grouting can be conducted in time to control soil thaw settlement.
