软土盾构隧道冻结施工试验研究

Experimental Research on Soft Clay Frozen in Shield-driven Tunnel

根据相似理论原理 ,在进行上海软土盾构隧道冻结加固模型试验之后 ,给出了盾构隧道冻结施工及盾构推进过程中土体温度、应力、变形的有关规律。

According to the analogy principle,the testing law of temperature,stress and displacement developments during freezing and shield working are given in this paper after the laboratory simulating tests on soft clay frozen in shield driven tunnel in shanghoi.The testing law may be served as a reference in Yanan East Road South tunnel under Huangpu river and city underground construction.
