摘要

台灣地區存在多處之卵礫石層，且愈來愈多的工程分佈於這些區域。為獲得較整體性之瞭解，本文說明各卵礫石層區域之材料性質及工程施工案例。首先依地區性將台灣西部卵礫石層分成六大分區，包括林口台地分區、苗栗分區、台中分區、大肚山分區、八卦山分區及竹山分區，分別探討其材料之物理性質及力學性質。於施工方面，主要討論工程上較常用者，包括深開挖、隧道（鑽掘工法）及灌漿。本文主要目的在提供卵礫石層之特性作為初步設計分析之參考。

With the increase of infrastructure development in Taiwan, more and more constructions will encounter the gravel formations. For a better understanding of the material properties of the gravel formations and the construction techniques, relevant data and cases are collected and reviewed. General discussions are provided in this paper. All data obtained are from the western areas of Taiwan and they are categorized into six groups based on the geological districts namely Linkou, Miaoli, Taichung, Tatushan, Pakuashan and Chushan. The material and engineering properties of the gravel formations are discussed. As for construction in gravel formations including excavation, tunnelling and grouting are all reviewed.
