铁路长隧道弃碴环境影响分析及其防治措施

Environmental Impact Analysis & Prevention and Harness Methods of Long Railway Tunnel Muck

在搜集有关资料和具体实践的基础上，系统地阐述了铁路长隧道由于弃碴占地引起耕地面积减少及水土流失、泥石流等生态环境问题，并提出相应的浆砌片石、干砌片石、码砌片石、片石笼及新型的塑料土工格栅工程防护措施与覆土造田、生物治理环保措施，以达到保护环境，防止水土流失的目的。同时提出了弃碴作为二次资源开发与综合利用的途径，使之变废为宝，化害为利，取得环境效益、社会效益及经济效益三统一。

Based on concrete practice and collecting of materials relative to it,thisarticle systematically illustrates the ecological problems caused by land occupancy of the long railway tunnel muck,such as agricultural acreage reduction,soil and water loss,mud and stone flow.The author also puts forward corresponding engineering protection methods,such as mortar rubble masonry,loose masonry,stone paving,stone piece held wire coop and type plastic geogrids,environment protection methods,such as garden making by earth covering,biological harness are also recommended to protect environment and to prevent soil and water loss.At the same time,the way in which the tunnel muck are exploited and comprehensively utilized as second resource is introduced to turn waste into treasure,harm into benefit,and to obtain integrated benefit of environment,society and economy.
