Abstract: This article introduces a new type of rapid detection technology of soil material characteristics-G-STAB system (referred to as falling ball detection technology). This technology is based on Hertz impact theory. By measuring the contact time between the falling ball and the ground, the automatic analysis software is Indexes such as the deformation modulus, foundation coefficient, and maximum compression of the test object can be calculated. A large number of indoor soil trough tests and field measurements have fully confirmed the test accuracy of the method and the good correspondence with the results of the plate load test, and can effectively guide the optimization of material grading, water content and rolling times during the filling process. The characteristics of falling ball detection technology are fast, effective, and low cost, which can well meet the comprehensive and real-time control of road engineering fill construction quality. The G-STAB test system developed by Japan Co., Ltd. (Tokyo) Co., Ltd. based on Hertz contact theory based on the rapid detection system of mechanical properties of soil materials G-STAB has a clear theoretical background, can quickly and accurately determine various types of soil-based materials ( (Clay, silt, sandy soil, gravel, modified soil, etc.) deformation properties and other mechanical properties.

The test operation of this technology is very simple, just drop the sphere, the analysis and calculation are all automatically completed, and the work efficiency is high (about a few seconds). Therefore, a small number of people can manage a large area of ​​the construction site, and the real-time inspection and control of the construction quality of road embankment filling and improved soil can be effectively performed.
The technology has been widely used in Japan's highways, environmental departments and power companies. In China, Sichuan Shengtuo Testing Co., Ltd. has obtained all rights related to the technology and has begun to produce equipment related to the technology. The following will give a detailed introduction to the test principle of the G-STAB system and its application in road engineering.
