摘要
分析国内常见孤石工程问题,弱化地质成因,依据工程特征将孤石分为3类,即残积层孤石、沉积层孤石和人工填石。在孤石分类的基础上,从勘察、盾构机选型和具体工程处理措施出发论述不同种类的孤石的处理对策。
Common shield engineering problems concerning encountered boulders are analysed and boulders are classified according to actual engineering situations and characteristics rather than geologic origins.Boulders are classified into settled layer boulders,residual layer boulders and artificial boulders.Based on boulder engineering classification,treatment measures are provided according to geotechnical investigation and surveying,shield selection and concrete engineering conditions.
