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:柏油的具体核心(ACC)水坝广泛地在中国被造。许多ACC水坝执行井,而是其它在此处学习的西方的中国包括盒子经历了重要的漏。浸透不饱和的水流动的一个数字模特儿被适应通过水坝模仿渗出物。由在不同条件下面比较正常、反常的渗出物地,为实际反常渗出物地的主要原因被识别并且在转变地区(TZ)和下游的水坝壳在ACC和非计划中的、低渗透层(LPL)归因于一个缺点。这些结论与水坝的状况和表演一致。不适当的ACC构造过程可能在ACC引起了缺点。ACC厚度的一个突然的变化可能导致了压力集中并且引起了ACC失败。为TZ和水坝壳的材料来源从说明,和土壤阶段复杂、变化因为TZ不充分地被控制。特别地,测试证明渗透在水坝的这二部分在大范围上变化。意外LPL可能在两个区域存在,并且连续地延长。
