摘要
以某市绿城路市政工程下穿350 km/h的高速铁路工程为例,研究了市政工程下穿高速铁路风险评估标准研究。通过有限元分析软件PLAXIS数值模拟,分析了复杂市政工程施工过程中高速铁路桥墩墩顶沉降变形、墩顶纵向水平变形、墩顶横向水平变形和桩基轴力的变化规律,并对绿城路市政工程的施工和运营风险进行了评估,为类似工程安全下穿高速铁路提供了参考。
Taking the municipal engineering of Lucheng Road underpassing 350 km/h high-speed railway projectin a city as an example,the risk assessment standard of municipal engineering underpassing high-speed railway isstudied.Through the numerical simulation of finite element analysis software PLAXIS,the settlement deformationof pier top,longitudinal horizontal deformation of pier top,transverse horizontal deformation of pier top and axialforce of pile foundation of high-speed railway during the construction of complex municipal engineering are ana⁃lyzed.The construction and operation risks of Lucheng Road municipal engineering are evaluated,which provides areference for similar projects to safely cross high-speed railway.
