摘要
高速铁路代表了世界铁路现代化发展的大趋势,是21世纪交通运输的重大成果,是人类的共同财富。随着经济的迅猛发展,交通运输需求激增,我国铁路客运专线建设已经进入一个高速发展的时期,由于高速铁路运行速度快、技术标准高、因此对路基的要求也很严格,严格控制路基变形已经成为客运专线路基的最大特点。路基变形最明显、危害最大的问题是路基沉降,而路基沉降控制是一个涉及因素较多、具有较大不确定性的工程难题。
路基沉降包括路基施工沉降和工后沉降,工后沉降尤其发生几率大、危害严重。本论文从路基沉降的原因、危害,控制路基沉降的措施、路基工后沉降的机理,控制路基工后沉降的必要性、步骤、措施、以及各种措施的特点,和路基沉降计算、监测等方面分析了路基沉降。

Abstract
High-speed railway represents the railway modernization development trend in the 21st century, is the important achievement of transportation, is mon wealth of mankind. Along with the rapid development of economy, the transportation demand, China railway PDL surge has entered a rapid development construction period , Due to the high speed railway running fast, high technical standards , so the roadbed of the strict control of sub grade settlement, has e the biggest characteristics of Sub grade of railway passenger dedicated line. The most obvious harm, roadbed deformation of the biggest problems is the embankment settlement. Embankment settlement control is one which involves many factors, has large uncertainties of engineering problems.
Embankment settlement including sub grade construction settlement and post-construction settlement, post-construction settlement risk , particularly serious harm , This paper from the nature and characteristics of loess embankment settlement, the reason and harm , the control measures of embankment settlement and roadbed settlement mechanism, Control of sub-grade settlement after the necessity , steps and measures, and the characteristics of measures, embankment settlement calculation, monitoring of embankment settlement.
KEY WORDS: High speed railway Sub-grade deformation Sub- grade settlement
