通过野外地表地质调查，建立了浙江省宁波市大榭岛地下储油罐区地表构造模型；结合浅层地震探测结果，研究了工程场区覆盖层厚度和基岩顶面埋深及深部构造特征。在此基础上，对场区的深、浅构造关系及地表和深部构造条件进行了综合分析和评价，认为：Ｆ１断裂可能从关外隧道西口北延到场区，并在近石弄堂一侧的海湾中入海；总的来说，除Ｆ１断裂带可能通过关外至石弄堂沿线附近，造成岩石连续性和完整性较差以外，场区其他大部分地区基岩的连续性和完整性较好；储油罐场区（应适当远离Ｆ１断裂）的透水性较差，是一良好的场址。
Based on the field surface geological survey, the surface structure model of the underground storage tank area in Daxie Island, Ningbo, Zhejiang Province was established. Combined with the results of shallow seismic exploration, the thickness of overburden and the burial depth of top of bedrock and the deep structural features . On this basis, the deep and shallow tectonic relationships of the site area and the surface and deep tectonic conditions are comprehensively analyzed and evaluated. It is concluded that the F1 fault may extend from the north west of Kwan O Tunnel to the field area and in the bay on the side near the alley In general, the continuity and integrity of bedrock in other parts of the site are better except that the F1 fault zone may pass near Guanzitang along the customs and lead to poor continuity and completeness of the rock. Oil storage The field plot (which should be well separated from the F1 fracture) has poor water permeability and is a good site.
