摘要:	本文係針對桃園縣南崁溪沿岸的河防工程，特別是石籠工程的破壞模式及一般缺失予以探討，石籠的破壞模式及一般缺失至少有下列六種類型，分別為基礎沉陷或背填土淘空破壞、石籠上下堆疊方式重力破壞、石籠兩端收尾方式破壞、填石材料不利綠化植生、滲透水造成堤內淹水、垃圾附掛污染環境等。經過整體分析研究的結論，針對石籠破壞模式及一般缺失，提出研究建議，諸如石籠基礎須埋設至低於現有河床高程以下，基礎以鋼筋混凝土興築，石籠堆疊施以鉤丁方式，收尾應如擋土牆般的施作直角翼牆，以上可增加石籠的安全性；石籠內填充細沙、土壤、植草包或植生毯加速綠化的成效；將纏繞的鉛線頭往內緣收頭，避免使其外露而勾結到漂流物，如此可避免纏留垃圾。 In this thesis, the failure modes of gabions and its general disadvantages to the conservation of Nang-Keng River are discussed. There are three kinds of failure modes of gabions. The first is the foundation settlements or the failure due to the wash-away of the backfill. The second is the failure due to the gravity of the stacking gabions. And the third is the failure due to the breakage of the ends of gabions. Furthermore, three disadvantages of gabions are identified. The first is the packing materials are unfavorable for planting. The second is the penetration of water makes the bank flooded. And the third is the environmental pollution due to the attachment of scraps on gabions. The following suggestions were concluded based on the results of systematic analyses. Firstly, the foundation of gabions should be buried below the high limit of the riverbed. Secondly, the foundation should be built by steel bars and concrete. Thirdly, the stacking of gabions should be secured in the form like bricklaying. Fourthly, the ending of gabions should be made as earth-retaining wall, which increases the safety of gabions. Fifthly, it is important to pack sand and soil in gabions and planting grass or seed-carpet to green the bank. Finally, making all the entangled lead wires go inward, that can prevent the attachment of scraps on gabions.
