对青岛胶州湾隧道超前地质预报工作的思考及建议

Comments on the Advance Geologic Predicton for Qingdao Jiaozhouwan Tunnel

超前地质预报工作应当编制相应的地质预报方案,海底隧道尤应如此。地质预报方案编制前,必须充分掌握熟悉隧道施工场区的地质背景条件,不同的地质背景,地质条件不同、地质复杂程度不同、勘察难度不同,因此有不同的地质预报方案。文章阐述了隧道超前地质预报工作的目的、性质以及编制超前地质预报方案的指导思想,着重强调地质观察研究在地质预报工作中的重要性。通过对超前预报相关合同文件所规定的预报手段的效用及特点的阐述以及人们对地质背景条件的不同认识,提出了胶州湾隧道不同的地质预报方案,同时对地质预报工作提出了建议。

The paper describes the objectives and features of advance geologic prediction and the guiding thought for compiling advance geologic prediction scheme. The importance of geologic observation and investigation in advance geologic prediction is stressed. The functions and features of predicting means stipulated in contract documents of advance prediction are explained and the different recognition of background geologic conditions by experts are considered. On this basis the authors present an unique option for the advance geologic prediction of Qingdao Jiaozhouwan tunnel with proposals for geologic prediction work put forward.
