A核电厂采用盾构法隧道取水，隧道内径达6200mm，为电力行业之最。盾构法取水隧道所穿越的土层相当复杂，尤其是起始段为局部基岩。A核电厂首次将新奥法引进到电厂取水盾构法隧道施工工艺中，成功地解决了土压平衡盾构机不适用于穿越局部岩基的难题，为今后电厂类似工程提供借鉴。
A覈電廠採用盾構法隧道取水，隧道內徑達6200mm，為電力行業之最。盾構法取水隧道所穿越的土層相噹複雜，尤其是起始段為跼部基巖。A覈電廠首次將新奧法引進到電廠取水盾構法隧道施工工藝中，成功地解決瞭土壓平衡盾構機不適用于穿越跼部巖基的難題，為今後電廠類似工程提供藉鑒。

A nuclear power station used water-intake shield tunnel, thetunnel’s inner diameter is 6200mm which is largest in power station. The soil stratums are very complex, especially at the initial segment in local bedrock. It’s the ifrst time to introduce New Austrian Method into the construction technology of water-intake shield tunnel in power station, successfully resolved the problem that the general shield machine is not suitable for local bedrock. This method can provide reference for similar projects in future power stations.
