简介:摘要:本文首先结合岩心编录、绘图分析及分析测试等资料,分析了齐齐哈尔地区姚家组沉积特征和沉积相类型及分布特征,在此基础上从砂岩型铀矿基础地质条件出发,全面分析了研究区姚家组铀矿成矿条件,认为姚家组埋深适宜、发育河道及三角洲平原分流河道砂体,且具有丰富的铀源、平缓东倾单斜构造、发育有良好的含水层和顶底板隔水层、较好的构造条件、完善的“补-径-排”体系,以及较多的铀异常显示,具备砂岩型铀矿成矿必备条件,具有一定的铀成矿潜力。

简介:摘要:随着我国经济和社会的日益发展,高强度预应力混凝土管桩以其单桩承载力高、生产周期短、施工方便快捷等特点被应用到国内的各个行业,如工民建、道路桥梁、水利水电及市政行业。但是,随着高强度预应力管桩工程应用的增多,相应也出现了各种各样的工程问题,例如管桩桩端未进入设计持力层导致承载力不足,压桩过程中桩体偏移、垂直度不满足规范要求,管桩连接节点质量差或者桩头构造不合理,导致抗拉拔承载力不足,打桩过程中出现爆桩或者桩身受损等问题。
