摘要: 傳統工地密度法採用砂錐法或橡皮膜法,由於取樣及相關量測程序步驟繁瑣。因此本研究之目的在於開發以彈簧為激發方式之新式貫入試驗法,以求快速且有效的檢測土壤工地密度。建立與土壤工地密度之關係曲線、貫入試驗法之靈敏度分析及檢測工地密度之可行性驗證。 本實驗材料為湖山水庫湖南壩壩體1a心層填築料、殼層料以及白水溪河堤填築料。在實驗室依三種含水量(OMC+2%、OMC、OMC-2%),使用不同夯實能量之材料進行貫入試驗,獲得率定曲線。在於現地施作貫入試驗,驗證率定結果。研究顯示利用尖頭貫入深度與平頭貫入深度差關係,可推估現地之含水量,進而估得工地密度。此研究成果可作為海河堤堤身、壩體防滲心層及殼層填築輾壓工地密度之檢測用,以確保施工品質。
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.
