根据室内系统的动三轴试验测定的砂砾石层液化所需的剪应力与计算的砂砾石层中不同深度处由地震引起的剪应力相对比，从而最终判定坝基是否液化，并根据该结论指导了坝基设计处理方案。
In view of the reservoir characters of severe heterogeneity , wide pore radius distribution , unpredictability of pore radius , and unrealized protection for whole hole section and bad protection effect by conventional shielding temporary plugging technology , we designed a broad spectrum oil film temporary plugging drilling and completion fluid system for reservoir protection
摘要针对油层非均质性强、孔径分布范围较宽、油层孔径难以准确预知，常规屏蔽暂堵技术几乎无法实现对整个油层井段的保护、油层保护效果差等特点，设计了广谱“油膜”暂堵型保护油层钻井完井液体系，并进行了室内系统评价和现场应用。
