研究目的:为满足客货运量运输需求并预留长远发展条件,部分线路近期修建为单线,预留双线建设条件,线路开通运营后择机适时增建Ⅱ线。单线预留双线铁路需统筹各区段近远期运输需求、Ⅰ线和Ⅱ线工程及实施条件,合理确定车站分布、Ⅱ线预留线位及近期同步实施工程。本文通过衢宁铁路线路方案研究,对单线预留双线铁路设计方法进行探讨。研究结论:单线预留双线铁路不仅需要设计好Ⅰ线,还需要预留好Ⅱ线条件。(1)应明确预留Ⅱ线同步实施工程范围,根据Ⅰ线的隧道、桥梁、车站等工程的难易程度,综合比选确定Ⅱ线的左右侧;(2)应尽量减少换侧的次数,并结合具体情况选择好换侧地点;(3)进行Ⅱ线工程预设计时应尽量减少预留Ⅱ线同步实施工程,确有必要时进行工程预留;(4)本研究可为类似单线预留双线铁路设计提供借鉴和参考。

Discarded train brake shoes mainly consist of steel-backed friction material. To be better reutilized, its essential features and its interaction in cement-based material need to be studied. Consequently, particle size analysis, SEM, IR and TGA were used to investigate two types of waste brake shoes, i e, mechanical grinding friction reclaimed material of waste brake-shoe（G-FRMWBS） and pyrolysis-friction reclaimed materials of waste brake-shoe（P-FRMWBS）. The latter exhibited less organic content, larger range of particle size distribution and smaller medium particle diameter. Both types contained inorganic particles of spherical and irregular shapes, striped with steel fiber. Upon isometric substituting fine aggregates, G-FRMWBS lifted the strength of mortar effectively that was increased by 16.6% and 17.5% when the replacing rate was 5%; the value went up to 19.2% and 19.2% when the replacing rate was 10%. Moreover, inclusion of FRMWBS enhanced the chloride penetration resistance, and optimized the pore characteristic and ITZ（interfacial transition zone） as well.
