Cone Penetration and Dilatometer Mobile System for Geo- technical Earthquake Engineering Research

这项行动是为了购买一台20吨的移动式圆锥贯入仪(CPT)和平板膨胀仪(DMT)系统，用于现场岩土现场勘察研究土壤动力学和减轻地震灾害。该设备目前至少用于密歇根大学的六个研究项目，即：(1)动载作用下无粘性土的刚性降低。(2)部分饱和砂土的研究。(3)用平板膨胀仪测得的应变剪切模数较小。(4)地震现场测试。(5)土体处理和设置土障的评价。(6)桩土相互作用。该移动系统为快速获取和处理高质量的岩土现场勘察数据提供了能力。这些信息被用于研究项目，并使用更传统或更新的技术来验证现场勘探的结果。

This action is for the acquisition of a mobile 20 ton Cone Penetration (CPT) and Flat Plate Dilatometer (DMT) system for in-situ geotechnical site exploration studies in soil dynamics and earthquake hazard mitigation. This equipment is being used on at least six current research projects at the University of Michigan, namely: (1) Reduction in stiffness of cohesionless soil due to dynamic loading. (2) Studies on partially saturated sands. (3) Small strain shear modulus by flat plate dilatometer. (4) Seismic in-situ testing. (5) Evaluation of soil treatment and constructed earth barriers. (6) Soil-pile interaction. This mobile system provides a capability for the rapid acquisition and processing of high quality geotechnical site exploration data. This information is used in research projects, and to validate the results from in-situ site exploration using more conventional or novel techniques.
