| 摘 要： | 京沪高速铁路全线以桥梁形式为主,在桥梁跨越既有公路时,必然涉及到对既有公路的影响,为了避免可能造成既有路基的沉降,通过对既有公路的沉降分析结合公路施工的相关规范确定了高速铁路承台施工措施来指导施工,最后通过沉降计算验证得出,所采取的施工措施能有效地防止既有路面的沉降,保证既有公路的安全通畅。

| Abstract: | Bridge is the main form of Beijing-Shanghai High Speed Railway Line.When the bridges cross existing roads, influence to the roads is unavoidable.To prevent the possible settlement of existing subgrades,in light of settlement analysis of existing roads and relevant road construction specification,pile cap construction of high-speed railway is fixed to guide the construction.Finally,settlement calculation proves that the adopted measures can effectively prevent subgrade settlement and ensure smooth and safe operation of existing roads. |
