A Review of Construction of Roadbed in High Speed Lines in China Combined with the Calculation of Pipe Load Subject to Traffic

摘要

The construction of railway and roadway, particularly of dedicated passenger line is well under way. However, the pipelines under the bed of railroad before could be disrupted due to the addition of soil strata as well as the influence of the construction. Considering the effects, the construction process of strata addition is summarized and the load calculation methods of pipelines, subject to traffic load, are summarized in the paper according to Chinese specifications relatively and the means abroad, which could be as references for design and construction hopefully.
