简介:为了与僵硬学习负担转移机制和混合堆积的适用的能力,核心(MPSC)被插入预制增强的具体堆积(PRCP)形成,在原处测试与不同长度,直径,水水泥比率和PRCP包含MPSC,水泥混合了堆积,并且钻洞堆积,被执行。限制适用的能力,负担解决曲线和MPSC的压力分发,混合堆积被获得。在水泥土壤和PRCP之间的负担转移被有限元素方法分析(女性)。测试结果和女性的分析证明MPSC充分从从外部顶装进转移内部水泥的PRCP的混合堆积和高压缩强度玷污的水泥利用了大磨擦,并且那插入进混合堆积的PRCP改变混合堆积的压力分发并且改进在混合堆积和土壤之间的摩擦抵抗。长度和MPSC的节区域onPRCP两个都有最佳价值。采用MPSC在改进软土壤地面的适用的能力是有效的。

简介:摘要:沥青混凝土心墙堆石坝为水电工程中常见坝型,在国内外均有广泛应用。沥青混凝土心墙作为大坝防渗建筑,其施工质量将直接影响到大坝坝体的防渗能力和使用寿命。然而,如何才能有效确保沥青混凝土心墙施工质量呢?本文通过巴基斯坦卡洛特水电站项目沥青混凝土心墙的实施案例,全面阐述了沥青混凝土心墙的施工过程,对类似项目在实施过程中的原料选用、工艺流程及技术参数等质量控制有较大的借鉴意义。
