【摘要】 本文介绍了一种用于岩土工程离心模型试验的，由微机和ＩＭＰ组成的数采系统。在煤层开采沉陷土体固结变形机理的模型试验中，克服由于离心机高速旋转而产生的离心力场，强电场和高频电等的影响，快速准确地在变形、位移、孔隙水压力等数据采集中，获得了理想的测试效果。更多还原

【Abstract】 his paper introduced a data sampling systemconsisting of a microcomputer and IMP. It maybe used for geotechnical centrifugal model experi-ments. In the modelling experiment of ″Themechanism of deformation during consolidation ofthe earth mass having subsided due to coalmining″. This system can overcome the influenceof the centrifugal force field preduced by high ro- tating speed,the intensive and high frequency elec-trical field; and can rapidly and accurately samplethe data of deformation, displacement and thepressure of pore water. Thus this system is to playan important role in getting the ideal experimentalresults.更多还原
