摘要:	近年來國內之交通量大幅度的提升，經由車輛荷重長期累積，造成鋪面本身平整度的下降，除了車輛荷重長期累積之外，國內對於管溝工程及下水道工程之需求增加，且常因管線埋設、維修或遷移等原因而進行道路挖掘埋設，進而影響鋪面之平整度，為了解決此項問題，政府單位也大力的推行道路齊平專案及人手孔蓋降埋等計劃。此外，露出道路表面之人手孔，其埋設間距過於密集，對於用路人行經時產生之震動感，明顯的對人體造成不舒適感。管線人手孔調整齊平或降埋作業後，產生人手孔周邊維護加固材料發生破壞，或因人手孔降埋致使路面發生破壞或毀損之現象，也對鋪面平整度造成影響。再經過電纜拉線之計算分析後，可考慮將目前法令所訂定之埋設長度限制拉長，以利減少人手孔蓋之數量。經由本研究敏感度分析模式求解結果整理及比較後，可充分瞭解在孔蓋施作齊平之情況下，道路平坦度受孔蓋數量多寡之影響較小，而孔蓋本身施作是否合乎規範值則對道路平坦度造成較大之影響。 In recent years, domestic traffic significantly increases the through long-term accumulation of vehicle loading, resulting in a decline in pavement roughness itself. In addition to long-term cumulative traffic load, the internal pipe trench for the sewer construction projects and an increase in demand, often due to pipeline laying , maintenance or relocation reasons and laying of road excavation, thereby affecting smooth of pavement, to resolve this issue, government units are strongly in the case of road smooth and set up manhole. In addition, the exposed road surface, depression, the laying interval is too dense for the use of pedestrians passing through the shock generated when a sense of the obvious discomfort of the human body. Pipeline flush or manual adjustment hole buried down after the operation, maintenance and strengthening of manholes produce material damage occurred, or manholes buried down the road led to destruction or damage occurring phenomenon, but also the impact on pavement smoothness. The calculation of cable pull for another analysis, consider the current set of laws laid length elongated, to facilitate the number of manhole covers to reduce manpower. After the research results of sensitivity analysis and comparison of sorting can be applied to fully understand the manhole covers flush with the case for road flatness covered by the hole the size of the effect of the number of smaller facilities for the manhole cover itself is a normative value of flatness of the road lead to a greater influence.
