为了扩大客运专线路基基床底层及以下部分路基本体填料的使用范围,基于客运专线路基静强度要求,对风化泥质粉砂岩的水泥改良土进行静强度试验,研究了不同的养生条件、龄期、压实度等因素对无侧限抗压强度的影响,论证了其水泥改良土作为客运专线路基填料的可行性,对客运专线的设计与质量控制具有指导意义。
In order to expand the use range of the basic block filler in subgrade and some of the following sections of passenger dedicated railway line, static strength tests were conducted on the cement-modified soil of weathered argillaceous siltstone based on the static strength requirements of the subgrade for passenger dedicated railway line. Different health conditions, , Compaction degree and other factors on the unconfined compressive strength. The feasibility of cement-modified soil as subgrade filler for passenger dedicated line is demonstrated, which has guiding significance for the design and quality control of passenger dedicated line.
