摘　　要：土工参数是工程设计、施工的重要依据,准确可靠的土工参数有利于节约工期,降低造价、保证质量,并大幅提高经济和社会效益。由于岩土介质复杂的多相性、碎散性和自然性特征,岩土工程测试技术对科学认知岩土各项物理力学指标,深入理解其工程力学性质起着极其重要的作用。从三轴压缩试验、离心模型试验、共振柱试验及热物性参数试验等方面,对室内土工测试技术研究新进展进行了阐释,并从静载荷试验、触探试验、旁压试验和十字板剪切试验等方面,对岩土原位测试技术及其应用研究进行了分析。伴随着岩土工程测试技术自动化、智能化、精细化水平的提高,岩土项目建设的质量和效益必将得以全面提升。Geotechnical parameters are an important basis for engineering design and construction. Accurate and reliable geotechnical parameters are conducive to saving construction period,reducing cost,ensuring quality,and greatly improving economic and social benefits. Due to the complex multiphase,fragmentation and naturalness of geotechnical media,geotechnical engineering testing technology plays an extremely important role in scientifically understanding various physical and mechanical indexes of geotechnical and deeply understanding its engineering mechanical properties.The new progress of indoor geotechnical testing technology is summarized from the aspects of triaxial compression test,centrifugal model test,resonance column test and thermophysical parameter test. The original testing technology and its application are analyzed from the aspects of static load test,penetration test,side pressure test and vane shear test.The improvement of automation,intelligence and refinement of geotechnical engineering testing technology will comprehensively improve the quality and benefit of geotechnical project construction.
