中文摘要 | 為了抒解台北都會區之交通量,並且兼顧使用者之行車安全性,東西向快速道路位於八里新店線段之基礎設計大量採用全套管基樁。因為用地限制及載重之需求,樁基礎多為大口徑之長樁。此一特性造成施工之困難度增加,而發生工程困難之風險亦同時增加。本文說明八里新店線A標段內工程於施工時所遭遇之基樁束管現象,尤其著重於樁號NO.1R及NO.2L於施作時發生束管之原因探討,包含探討此區域之地質特性、全套管基樁施工特殊需求、基樁承載力設計相關規定等。而後根據討論結果,提出此區域之基樁承載設計相關建議。 |
英文摘要 | In order to alleviate the traffic congestion problem among the Taipei metropolitan areas, the Bali-Shinden line of East-West Expressway System project is designed to satisfy both the traffic volume and also the safety of driving during the rush hour traffic. This project is designed with the long and large-diameter pile, which increases the risk of occurrence of construction difficulty. The construction difficulties occurred during the casings installation of pier numbers of NO.1R and NO.2L, in which cases, casing were restrained by the surrounding soil and thus stopped the machine from further driving and withdrawing the casing. This paper summarizes the event of this construction difficulty and investigates its causes by reviewing the local geology and pile design process. The discussion at the end of paper provides possible causes of the restrained casing situation and suggests possible revisions for future pile design. |
