摘要

为明确标定罐模型试验在室内模拟原位测试技术领域中的研究现状,根据国内外大量文献中相关标定罐模型试验的报道,对现今世界上已有的大型标定罐进行了总结,并对比分析了各个标定罐的优缺点以及标定罐的改进历程。介绍了国内外使用最为广泛的两种标定罐体系的相关研究内容,论述了影响标定罐模型试验的相关参数以及影响因素,并归纳了标定罐试验的应用研究结果。分析结果表明,标定罐模型试验在原位测试技术的应用研究具有很好的应用前景,且集边界条件控制、应力状态控制、土样控制等各种特点于一身;通过标定罐试验进行相关的土体参数的推算与验算,与之相应的原位试验进行对比,分析了不同土层的现场经验公式,可为原位试验的评价与分析提供依据。但是,标定罐试验的相关研究还需进一步的加强与扩展,目前主要是砂质土的相关研究,对于黏性土和特殊土尚缺少相关研究;原位测试参数方面也应加强对侧摩阻力、孔隙水压力等相关参数的试验研究。

Abstract

In order to define the status of calibration tank model test in the field of laboratory tests simulating in-situ technology research, the paper summarizes the world's existing large calibration tank according to extensive literatures at home and abroad that related to calibration tank model test report. Besides, the relevant research content of two most widely used calibration tanks at home and abroad are summarized after analyzing the advantages and shortcomings as well as the improvement process of each calibration tank. Meanwhile, the effect of related parameters and influencing factors is discussed; and the application results of calibration tank test are summarized. The analytical results show that the calibration tank model test research has a good application prospect on the applied research of in situ testing technology; and it combines the merits of boundary conditions control, the stress state control and soil sample control in one. Based on calibration tank test data, soil parameters calculation and checking are performed; and the empirical formula of different soil layers is analyzed compared with in-situ test. It provides the basis for evaluation and analysis of the in-situ test. However, the related research of calibration tank test still need to further strengthen and expand, i.e. the present main research is about sandy soil, less on the study on the cohesive soil and special soil. While in-situ test may strengthen the study on the parameters such as friction and pore water pressure.
