摘　　要：梅纳旁压仪属于纯进口仪器,在中国水电行业应用较晚,而水电行业规范是根据中国国产旁压仪的特点及性能编制的,其能否适用于梅纳旁压仪是值得探讨的。通过对国内外规范的对比分析,阐述了梅纳旁压仪在测试坝基深厚覆盖层力学参数时存在的问题,并依据实践经验,提出了一些有针对性的建议,为以后工程提供一些借鉴。The imported Menard pressuremeter is lately applied in hydropower industry in China. But, codes for hydropower industry are compiled based on the features and performance of the pressnremeter made in China. Whether those codes can be applicable to Menard pressuremeter need study. Through the comparison and analysis of domestic and international codes, potential issues on Menard prssuremeter for testing the mechanical parameters of deep overburden are described. Furthermore, tips on application of Menard pres- suremeter, based on actual engineering practice, are provided for future projects.
