陡坡段桩柱式桥梁的基桩受力分析与施工研究

Stress Analysis and Construction of Pile Foundation at Steep Slope Section of Bridge

随着社会经济的不断发展,陡坡段桩柱式桥梁的基桩也被广泛应用于西部山区。但是,与平原地区不同,西部山区的地形和环境等较为复杂,这就使得其陡坡段桩柱式桥梁基桩的承载力容易受多方面因素的影响,从而给该类工程建设带来了一定的难度。因此,加强对其受力情况与施工的研究尤为重要。论文通过分析基桩的承载特性,设计了相应的简化受力模型,进而对其水平位移与受力情况进行了具体推导。再通过列举某山区的实际工程,来对其滑坡推力、基桩内力、桩端末平衡弯矩、进行实际的计算与验证。由此可知,加强对陡坡段桩柱式桥梁基桩的防护、加固与维修,能够有效促进桥梁工程的顺利进行,并确保其使用过程中的安全性。

The new period, with the continuous development of society, the pile at steep slope section of bridge has been widely used and western mountainous areas.But,Different from plain area, the western mountains terrain and the environment is more complex, which makes the steep slope section of pile column bridge pile bearing capacity are easily influenced by many, which to the construction of the project brought a certain degree of difficulty.Therefore, it is particularly important to strengthen the study of its stress and construction.Through analysis of pile load bearing characteristics, design the corresponding simplified mechanical model, and on the horizontal displacement and stress of concrete is. Followed by listing somewhere in the mountains of practical engineering, to thrust, pile internal force, pile end moment equilibrium, the actual calculation and verification of the landslides in the.And thus it may be known, strengthen protection of steep slope section of pile column bridge pile, reinforcement and maintenance, can effectively promote the smooth progress of the bridge engineering, and to ensure the use of safety.
