随着经济的不断发展和社会的不断进步,城乡差距逐渐缩小,城市化的脚步逐渐加快,为进一步促进城乡交流,广泛建造公路桥梁已经成为现代社会发展和经济进步的一项重要标志。但是我国地域广阔,广布着不同的地质地貌类型,对公路桥梁的建设具有一定的影响。软土地基渗透性差、含水量高、抗剪强度差,不利于路桥施工稳固性。本文以路桥软土地基施工为例,针对公路桥梁在软土地基施工的基本概况、公路桥梁软土地基施工的技术要点和注意事项进行探讨。
With the continuous economic development and social progress, the gap between urban and rural areas is gradually narrowing and the pace of urbanization is gradually accelerating. To further promote the exchange between urban and rural areas, extensively building road bridges has become an important symbol of modern social development and economic progress. However, China has a vast territory and a wide range of different types of geology and geomorphology, which has a certain impact on the construction of highway bridges. Soft soil foundation permeability is poor, high water content, shear strength is poor, is not conducive to road construction stability. Taking the construction of soft soil foundation in Luqiao as an example, this paper discusses the basic general situation of highway bridges and bridges in soft soil foundation construction and the technical points and precautions of soft soil foundation construction in highway bridges.
