路塹橋墩深基礎開挖PC STABL6模擬分析

為解決國道1號五股至楊梅路段長久以來塞車導致服務品質低落，間而影響經濟的問題，推動執行「國道1號五股至楊梅段拓寬工程計畫」如火如荼的展開，但在用地取得上是影響計畫甚鉅的因素之一，因而有落墩在原有國道1號路塹之設計。為維持中山高速公路用路人安全，路塹落墩處深基礎開挖之擋土工法，在泰山林口段計有型鋼襯板擋土，土釘逐階降挖擋土，井式基礎加竹削擋土工法，本報告即利用監測系統之數據針對此三種型式擋土工法，比較其對路塹開挖之穩定性，並利用開挖時中山高速公路側路面發生細微裂痕時墩位之監測數據，加以邊坡穩定程式極限平衡法的STABL軟體比對前人對卵礫石層參數之經驗值推測現地凝聚力C，摩擦角ψ之數據。

In National Highway No. 1 Wugu to Yangmei Section, there is always heavy traffic and low qualities of service for a long time. The economy is affected indirectly. To Solve those problems, The “National Highway No. 1 Wugu to Yangmei Section Widening Project" is executed in full swing. Land expropriation is one of the important keys on this project. So the piers are designed on the cutting of National Highway No. 1. To maintain the traffic safety in National Highway No. 1, there are three retaining methods using to the foundation excavation on the cutting in Taishan-Linkou section: H-section steel and sheetpile retaining method, soil nailing method, and well foundation method. In this article, stability of cutting excavation will be compared to those three retaining methods by the data of monitoring system. Then import those data to STABL to find the cohesion C and friction angleψ.
