摘要
目前大部分岩土工程勘察企业使用的是传统原位测试手段。为了梳理、归纳岩土原位测试技术的最新进展,从变形特性试验、抗剪强度试验、渗透试验和触探试验等四个方面,将20世纪90年代至今岩土原位测试技术与设备的最新研究进展进行系统性综述。当前的原位测试技术具备自动化、信息化、多功能化和技术升级等四大特征,但仍然存在测试成本高、理论基础薄弱、试验自身局限和进展缓慢等问题。根据实际问题从加强理论基础、信息化和多功能设备的研发、拓展研究区域等方面提出展望。
At present,most geotechnical engineering survey enterprises use the traditional in-situ testing method.In order to summarize the latest development of geotechnical in-situ testing technology,the latest research progress of geotechnical in-situ testing technology and equipment since 1990s are analyzed from four aspects,including deformation characteristics test,shear strength test,permeability test and penetration test.The results show that the current in-situ testing technology has four characteristics:automation,informationization,multi-function and technology upgrading,but there are still some problems,such as high cost,weak theoretical basis,limitations of the test itself and slow progress.According to the practical problems,prospects are put forward from the aspects of strengthening the theoretical basis,accelerating information technology and multi-functional equipment research,expanding the re-search area and so on.
