摘要：围岩荷载的确定是进行隧道工程衬砌结构设计的关键。现行铁路隧道规范中深埋隧道围岩荷载计算公式是根据单线铁路隧道施工塌方的调查统计资料建立起来的统计经验公式,多年来,对于指导单、双线铁路隧道的结构设计起到至关重要的作用,但用于指导当前三线,特别是四线铁路隧道时,就显得无能为力了。提出一种合理的适合于三线、四线甚至更大跨度的铁路隧道的围岩荷载计算方法,提出考虑围岩变形全过程的"统一围岩压力曲线",并基于贵昆铁路六盘水至沾益段增建二线上的乌蒙山2号四线车站大跨度隧道,开展现场试验,对围岩压力进行监控量测,结合统一围岩压力曲线,提出竖向围岩压力计算公式q=Kγha。

摘要：采用理论分析和数值模拟手段,开展跨度对围岩稳定性的影响规律研究。结果表明,在开挖后仅出现弹性二次应力状态条件下,单纯的增加隧道开挖跨度而不改变断面形状对围岩应力状态影响不大,但若开挖后形成塑性区,则即使不改变断面形状,单纯加大开挖跨度也会大大增加塑性区半径,影响围岩稳定。通过对乌蒙山2号四线铁路隧道深、浅埋工况毛洞破坏模式的对比分析,建议浅埋工况支护以刚度要求为主,减小释放,控制沉降,深埋工况支护以强度要求为主,适当释放,变形可控。

摘要：杭州市七格污水处理厂设计处理规模为150×10^(4)m^(3)/d,污泥产量约1600 t/d(含水率为80%),为解决污泥处理能力存在较大缺口的问题,实施了污泥处理提升工程。采用化学调理和板框压滤的方式进行污泥深度脱水,脱水后可通过焚烧、建材利用等处置方式,有效实现污泥的减量化、稳定化、无害化、资源化。目前,该工程运行稳定,出泥含水率可控制在50%以下,污泥减量50%以上,其设计和运行经验具有一定的借鉴意义。
