由山东省水科所承担的“堤坝地基劈裂灌浆防渗技术”和“土坝坝体劈裂灌浆浆液性能的试验研究”二项研究课题,于1988年12月22日至24日在山东省济南市召开了成果鉴定会。“堤坝地基劈裂灌浆防渗技术”,是利用堤坝地基应力场的分布规律和水力劈裂原理,在一定的灌浆压力作用下将堤坝地基劈裂并灌注适宜的浆液,形成铅直连续的浆体防渗帷幕,以达到防渗加固的目的。鉴定会认为“本课题选题重要、恰当,对堤坝除险加固有重大价值”,“在土
From the Shandong Provincial Department of water borne “dyke foundation split-grouting seepage control technology” and “earth dam fracturing grouting slurry performance test” two research topics, in December 22, 1988 to 24 in Shandong Jinan City, held a results appraisal meeting. “Embankment foundation split-grouting anti-seepage technology” is the use of the foundation of the dam foundation stress distribution and hydraulic fracturing principle, under certain grouting pressure to embankment dam foundation and perfusion appropriate slurry to form a vertical continuous slurry Anti-seepage curtain in order to achieve the purpose of impermeable reinforcement. Appraisal will think that “the subject of this topic is important and appropriate, of great value to the reinforcement of dikes,” "in the soil
