摘要

为解决盾构隧道施工过程中孤石带来的风险，以台山核电站取水隧洞工程为例，介绍了孤石对盾构施工的危害及处理措施，从物探方法、探测设备、探测范围等多个方面介绍了探测技术，证明采用地震反射波CDP叠加技术进行孤石探测是可行的，并通过钻孔验证了物探成果的准确性。尤其对于1 m以上的孤石探测较为准确。

Abstract

The successful boulder prospecting by means of marine seismic reflection CDP stacking technology adopted in the construction of the waterintake tunnel of Taishan Nuclear Power Station is analyzed, so as to reduce the construction risk of shieldbored tunnel in bouldercontaining strata. The practice demonstrates that the geophysical prospecting technology adopted is feasible for prospecting boulders under water, especially for the detection of boulders with diameter being larger than 1 m.

Key words： seacrossing tunnel; shield tunneling; boulder prospecting; pretreatment; seismic reflection wave
