摘要

随着上海地下空间的开发利用，冻结法越来越广泛地用于隧道建设中。为了避免冻结法施工中可能产生的地质灾害问题，有必要对上海软土地区的土体冻融过程中物理力学性能进一步地研究。通过对上海软土某工程3种不同的土样原状土、一次冻融土、二次冻融土进行不同状态下土力学试验，得到了土体在二次冻融循环作用下物理力学特征的变化规律。研究结果对隧道的设计提供了有价值的参考。

Abstract

With the development of underground space in Shanghai

the ground freezing method is more and more widely used in tunnel construction. In order to avoid the problems of geological disaster which may happen in the freezing construction

it is necessary to do more researches on the physico-mechanical characters of Shanghai soft soil under freezing and thawing action. The characters of three kinds of soils from a certain project in different states (original state

freeze-thaw state

secondary freeze-thaw)

are stadied; and the change rules of soil characters under secondary freeze-thaw action are educed. The results will be beneficial to the safety of the tunnel construction.
