Description

轻型桥台light abutment

技术领域technical field

本实用新型涉及桥梁领域,具体涉及一种轻型桥台。The utility model relates to the field of bridges, in particular to a light abutment.

背景技术Background technique

随着我国国家高速公路网规划的实施及完善,目前山区高速公路建设项目越来越多。由于山区地形陡峻,桥台往往设置于较陡的路堑边坡上,这些位置地质条件复杂多样,使得山区桥台设计成为桥梁设计的重点。With the implementation and improvement of my country's national expressway network planning, there are more and more mountainous expressway construction projects. Due to the steep terrain in mountainous areas, abutments are often set on steep cutting slopes. The geological conditions of these locations are complex and diverse, making the design of abutments in mountainous areas the focus of bridge design.

桥台是桥梁的重要组成部分,它除了支撑桥跨结构外,还有衔接两岸道路的作用,既要能挡土护岸又要承受台后填土压力及车辆荷载产生的附加土侧压力。因此,不仅要求桥台本身具有足够的强度、刚度和稳定性,而且对地基的承载力、沉降量、地基与基础之间的摩阻力等也有一定的要求。The abutment is an important part of the bridge. In addition to supporting the bridge span structure, it also has the function of connecting the roads on both sides. It must not only retain the soil and revetment, but also bear the pressure of the filling soil behind the abutment and the additional soil lateral pressure generated by the vehicle load. Therefore, not only the abutment itself is required to have sufficient strength, stiffness and stability, but also the bearing capacity of the foundation, settlement, and the frictional resistance between the foundation and the foundation are also required.

目前山区高速公路建设中常用的桥台形式主要为重力式U形桥台、桩柱式桥台以及肋板台。At present, the abutment forms commonly used in the construction of mountainous expressways are mainly gravity U-shaped abutment, pile abutment and rib abutment.

重力式U形桥台主要缺点有:1)桥台体积与自重较大;2)桥台一般采用大体积的浆砌片石或片石砼,施工质量较难控制。3)随着桥台高度增加,对桥址区承载力要求也较高,适用于地基承载力较大,填土高度8-10米以下大中桥梁;4)当桥台处于纵横坡度较陡的地方,为了保证基础的安全距离,防止基础脱空,一般会将基础埋置较深,将桥台设计得较高,使得桥台处开挖量大大增加,形成较高的边坡,从而增加防护工程量。The main disadvantages of the gravity U-shaped abutment are: 1) the volume and self-weight of the abutment are large; 2) the abutment generally adopts large-volume grouted rubble or rubble concrete, and the construction quality is difficult to control. 3) As the height of the abutment increases, the requirements for the bearing capacity of the bridge site area are also higher, which is suitable for large and medium-sized bridges with a large foundation bearing capacity and a filling height of 8-10 meters; 4) When the abutment is on a steep vertical and horizontal slope In some places, in order to ensure the safe distance of the foundation and prevent the foundation from falling out, the foundation is generally buried deeper and the abutment is designed higher, which greatly increases the excavation volume at the abutment and forms a higher slope, thus Increase the amount of protection works.

传统的桩柱式桥台以及肋板台主要缺点是桥台前需设置锥坡,特别是在山区公路上,坡面陡峭、地形复杂导致桥台锥坡体量较大,如果锥坡坡率与原始地面坡率接近,锥坡设置困难,锥坡无法施工压实,对地形的改造较大,对环境破坏也较大;或者深入挖方造成边跨浪费,且容易引发边坡失稳等次生灾害等。The main disadvantage of traditional piled abutments and ribbed abutments is that a conical slope needs to be set in front of the abutment, especially on mountainous roads. The steep slope and complex terrain lead to a large volume of abutment conical slope. The slope ratio is close to that of the original ground, and it is difficult to set up the conical slope. The conical slope cannot be constructed and compacted, and the transformation of the terrain is relatively large, and the damage to the environment is also large; or the side span is wasted due to deep excavation, and it is easy to cause slope instability, etc. Disaster etc.

重力式U形桥台通常需要对山体有较大的开挖,对山区的植被有很大程度的破坏。桩柱式桥台以及肋板台通常需要设置锥坡来保护桥台结构的稳定,大体量的桥台锥坡对山区环境和地表植被的破坏同样巨大。不符合“资源节约型社会、环境型友好型社会”两型社会的核心建设理念。Gravity-type U-shaped abutments usually require large excavations on the mountain, which will greatly damage the vegetation in the mountainous area. Pile-type abutments and ribbed abutments usually require conical slopes to protect the stability of the abutment structure. Large-scale abutment conical slopes also cause great damage to the mountainous environment and surface vegetation. It does not conform to the core construction concept of "resource-saving society and environment-friendly society".

以前设计或者建造的桩柱式桥台,耳墙一般设计为梯形,常常需要借助大体量锥坡来保证桥台结构的整体稳定性,在山区人工构造的锥坡严重破坏了桥台周边的生态环境。In the pile-type abutments previously designed or built, the ear walls are generally designed in a trapezoidal shape, often requiring the use of large-scale conical slopes to ensure the overall stability of the abutment structure. The artificially constructed conical slopes in mountainous areas have seriously damaged the ecology around the abutment surroundings.

综上,亟需一种设计简单、自重较轻、质量可控、施工便利且在建造时不需要大面积破坏生态的(不需要设置锥坡或开挖山体等严重影响环境的现象)用于山区的桥台。In summary, there is an urgent need for a design that is simple in design, light in weight, controllable in quality, convenient in construction, and does not require large-scale ecological damage during construction (no need to set up cone slopes or excavate mountains and other phenomena that seriously affect the environment) for use in Abutments in the mountains.
