摘要
随着城市交通拥堵问题日益严重,修建地下工程和对地下空间进行开发成为了主要的解决办法。早期地铁工程没有纳入城市规划,使地铁修建时其线路经常会从既有建筑物下面穿过,给建筑物基础承载能力造成一定的损伤,通过基础托换能够使这类问题得到较好的解决。论文以狮岭公园人行天桥为例,依据工程地质和水文情况,分析桩基托换设计的原则、结构设计、系统计算等,为类似工程提供参考。
With the increasingly serious problem of urban traffic congestion, the construction of underground engineering and the development of underground space has become the main solution. Earlyno subwayproject into the cityplanning, the subway line in the construction often from existing buildings following through, this will give the building foundation beating capacity to cause some damage, the underpinning can make this kind of problem will be solved. The Shiling Park pedestrian bridge as an example, the engineering geological and hydrological conditions are introduced, and then analysis the pile foundation underpinning the design principle, system structure design, calculation, provide a reference for similar projects.
