第八章 結論與建議
8.2 建議
1. 點雲模型的不連續面分析,目前只針對位態及空間位置作探討,未來若可細分 每組節理組各自的間距,甚至發展出一套流程,定義一露頭中節理組的延續性,
將可更有效提升以攝影測量進行岩坡節理性質調查的成效。
2. 針對多組節理組形成之楔形破壞,本研究雖已探討節理延續性、節理面交角、
不對稱性及傾伏角等控制因子,但岩石邊坡工程中所在意之節理幾何性質仍尚 有節理間距、組數、跡長等因素,未來可針對上述特性作影響性評估。
3. 本研究目前只探討影響楔形岩體形成之節理幾何性質,尚未針對節理弱化或是 節理延伸等因素影響,未來可嘗試在不同節理幾何性質下,一併探討降雨、地 下水等水文影響,以在模擬中加入驅動塊體崩落之因素,以更接近現地之真實 情況。
4. 有鑑於過去對楔形破壞產生落石群之機制研究甚少,當一岩石邊坡之節理組持 續發展,其邊坡工程及周圍人工構造物之相關設計,該如何採取相對應的措施,
亦應是未來探討的一大方向。
