排导槽是泥石流治理常用的工程措施,泥石流若在槽内淤积,将极大影响排导槽防治效果。目前国内现行规范中没有关于排导槽淤积情况计算的相关条款,导致排导槽被泥石流淤埋的工程事故时有发生。鉴于此,分析了排导槽淤堵的常见原因,对现有的一些排导槽淤积验算公式进行了分析和整理,提出了一套基于槽宽验算、槽内泥深及流速验算等公式的排导槽防淤设计验算方法。该方法在雅(安)泸(沽)高速公路沿线某泥石流沟V型排导槽淤埋事故的处理中进行了应用,重建的排导槽经受了2011年6月17日特大暴雨形成的泥石流的考验,说明该方法实施效果良好,可供相关研究与设计参考。 相似文献

Six different environmental samples were applied to enrich microbial consortia for efficient degradation of corn stalk,under the thermophilic and mesophilic conditions.The consortium obtained from anaerobic digested sludge under thermophilic condition(TC-Y)had the highest lignocellulose-degrading activity.The CO_2yield was 246.73 m L/g VS in23 days,meanwhile,the maximum CO_2production rate was 15.48 mL/(CO_2·d),which was28.75%and 52.27%higher than that under mesophilic condition,respectively.The peak value of cellulase activity reached 0.105 U/mL,which was at least 34.61%higher than the other groups.In addition,49.5%of corn stalk was degraded in 20 days,moreover,the degradation ratio of cellulose,hemicellulose and lignin can reach 52.76%,62.45%and42.23%,respectively.Microbial consortium structure analysis indicated that the TC-Y contained the phylum of Gemmatimonadetes,Acidobacteria,Chloroflexi,Planctomycetes,Firmicutes,and Proteobacteria.Furthermore,the Pseudoxanthomonas belonging to GammaProteobacteria might be the key bacterial group for the lignocellulose degradation.These results indicated the capability of degrading un-pretreated corn stalk and the potential for further investigation and application of TC-Y. 相似文献
