The sand cone method and the rubber balloon method are widely used to determine the field density of soil compaction. The main disadvantage of these two traditional methods lies in its numerous and trivial procedure in sampling and related measurement. As a result, this thesis aims to develop a spring-loaded pin penetration test method for quick examination of the soil compaction density at the construction sites. Moreover, the focus of the thesis includes developing the relationship between the pin penetration depth and the soil compaction density, analyzing the sensitivity of penetration test method, and testing the practicability of measuring the field density. The experiment materials comprise core layer of Hushan reservoir dam, shell layer of Hushan reservoir dam, and embakment of White-water River. To get calibration curve, various compaction efforts are applied to the experimental materials with three distinct moisture content (OMC+2%、OMC、OMC-2%). Finally, the penetration tests are performed at construction sites to evaluate the soil compaction density. The experimental results show that by comparing the depth differences between the cone-head penetration test and flat-head penetration test, one can identify the moisture content status at the construction sites and further estimate its density. The experimental results presented in this thesis can be applied in the core layer of Hushan reservoir dam, the shell layer of Hushan reservoir dam and embankment of White-water River to assure the quality of construction.
