摘要:
为分析复杂地质高速铁路采用人工挖孔桩+便梁支护后的安全性，本文以杭深铁路莆田站站区人工挖孔桩工程为依托，采用有限元软件研究了列车振动荷载作用下桩体结构的变形，提出了运营高速铁路站区内人工挖孔桩施工关键技术。结果表明：（1）列车的振动荷载下桩体的位移仍处于安全范围内；（2）高速铁路站区内人工挖孔桩施工技术能够在复杂地质及建筑物环境下有效地缩短施工时间，提高施工效率，降低施工空间要求，保障施工安全；（3）现场应用验证了人工挖孔桩施工关键技术的可行性、安全性，该技术可为类似工程提供参考借鉴。
Abstract:
In order to analyze the safety of high-speed railways in complex geological conditions after adopting hand-dug piles + temporary beam support，a case study was conducted based on the hand-dug piles in Putian Station Area of Hangzhou-Shenzhen Railway in this paper，and the finite element software was used to study the deformation of pile structure under the vibration load of trains，and key construction technology of hand-dug piles in the station area of high-speed railways in operation was put forward. The results show that：（1）The displacement of pile body under the vibration load of trains is still within the safe range.（2）The use of hand-dug piles in the station area of the high-speed railway can effectively reduce the construction time，improve the construction efficiency，reduce the construction space requirements and ensure the construction safety in complex geological conditions and building environments.（3）The feasibility and safety of the key technology of hand-dug piles are verified by field application，and the conclusions can provide a reference for similar projects.
