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

这一行动是为了获得一个20吨的移动锥形穿透（CPT）和平板膨胀仪（DMT）系统，用于土壤动力学和地震减灾的原位岩土工程现场勘探研究。密歇根大学目前至少有六个研究项目正在使用这种设备，分别是：(1)动荷载作用下无黏性土的刚度降低。(2)部分饱和砂土的研究。(3)平板膨胀仪应变剪切模量小。(4)地震原位试验。(5)土壤处理和土方屏障的评价。(6)桩土相互作用。该移动系统提供了快速获取和处理高质量岩土工程现场勘探数据的能力。这些信息用于研究项目，并使用更传统或新颖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.
