摘要

國內外有關於礫石土材料之大顆粒材料力學試驗發展至今，已累積相當之經驗，然而現有之礫石土材料力學試驗結果因離散性過大及試驗本身適用性問題，不論在力學行為瞭解或實際工程應用上均有爭議性。本文針對礫石土材料之國內外室內與現地力學試驗過去的發展及現況作一整理，並對礫石土材料力學試驗目前於工程上之應用及未來可能之發展提出建議，以供地工界朋友參考。

A significant amount of experience has been accumulated through years of research and development in characterizing the mechanical properties of gravel materials. However, due to deficiencies of experimental procedures and the scattering nature of test results, there are many controversial issues related to the fundamental mechanical behavior as well as practical applications of gravelly soils. This paper summarizes current domestic and overseas development efforts in laboratory and in-situ experiments on gravelly soils. Possibilities of applying these experiments in engineering practice and their future development are recommended to our peers for their reference.
