| 摘 要： | 云南星云湖出流改道隧洞工程的桩号11＋000～11＋120段为粉砂质黏土夹粉细砂地层。此处施工，多次涌水涌砂，不能成洞。后采用冷冻法固结土体，隧洞因此得以顺利贯通。冷冻法固结土体虽然昂贵，但有效、可靠，局部使用的话还是可以承受的。

| Abstract: | The section between Pile No. 11 ＋ 000 - 11 ＋ 120 in the Xingyunhu Lake outflow rerouting construction is the mixture layer of silty clay and fine silt. The quick inflow of sand and water occurred several times and disabled the formation of the tunnel. The freezing method was used to consolidate the soil body and enabled the opening of the tunnel. The freezing method was proved to be effective and feasible. Thought it is somewhat expensive, it is worthwhile and affordable if used in part of the construction. |
