摘要:
为确保高速铁路路基工程在深厚湿陷性黄土纵深地区的沉降变形得到有效控制，文章通过大量理论计算、经验总结及试验研究，提出了有砟轨道高速铁路路基工程在湿陷性黄土地基中的沉降变形综合控制技术，具体通过地基处理挤密地基土，消除全部或部分湿陷性，配合严格的防排水设计，提高复合地基承载力，控制工后沉降量、剩余湿陷量和路基本体预留沉降量的总和满足规范要求，从路基沉降变形三源头控制其沉降变形总量，对湿陷性黄土地区类似工程设计具有指导意义。
Abstract:
To ensure the settlement and deformation of high-speed railway subgrade can be effectively controlled in deep collapsible loess region, through a large number of theoretical calculations, experience summary and experimental study, integrated control technology of settlement and deformation of high-speed railway subgrade in collapsible loess region is put forward. Specifically through ground treatment compacted foundation soil, eliminating all or part of the collapsibility, with strict anti-drainage design, improving the capacity of composite foundation, by controlling the settlement sum of post-construction settlement, remnant collapse and subgrade body reserve settlement to fulfil the requirements of the code. Controlling the total amount of settlement and deformation from 3 sources has a guiding significance for similar projects in collapsible loess region.
