【摘要】 堤防劈裂灌浆技术主要是根据堤基、堤身应力场分布特性和水力劈裂原理，利用注浆机械在注浆过程中形成的注浆压力将堤防连同其堤基沿轴线方向劈开，随之灌入浆液，固结后形成垂直纵向连续的帷幕，达到截断堤身渗漏通道，增加堤基渗透路径的目的。同时还具有充填堤身内部洞穴和裂缝，消除堤防隐患的功能。 本论文是作者在主持并完成渭河下游左岸西安市临潼区西渭阳堤段劈裂灌浆加固试验后撰写的一份技术总结材料。通过试验不仅证明利用劈裂灌浆技术在渭河堤防内，能够形成符合设计要求的，铅直连续的浆体防渗帷幕，防止堤防在高水位时的渗透破坏；同时在处理堤防孔洞、裂缝及松散夹层等隐患方面效果也很显著。另外，通过本次实践，也摸索出了一些适合渭河堤防劈裂灌浆施工的技术参数和经济指标，为我省量大面广、挡水不深的堤防工程除险加固提供了一种新的途径和方法。更多还原

【Abstract】 The embankment is chop to crack pours and is starched the technique chiefly is on the basis of the embankment foundation Embankment body stress field distribution property and hydraulic power chops cracks the rule, Utilizing the notes to starch machine to be living to explain with notes that in the thick liquid process take shape to starch pressure along with such embankment foundation along the axial line orientation chops to turn on the embankment, Pour into thick liquid at the same time , Solidifying queen takes shape the successive heavy curtain of vertical machine direction , Attaiing blocks the embankment body seepage passageway , Add the aim that the embankment foundation seeps the way. The at the same time still has fills embankment body inside cave and the split , Remove the embankment hidden danger meritorous service capacity.This dissertation is that writer is living to manage the technique summing-up stuff pouing thick liquid the consolidating eperiment afterwards to write completeed the left wing coast Xi’an Lintong district of Weihe River downsteam Xi Weiyang embankment Duan Pilie. By means of the eperiment not merely demonstrate to utilize chops cracks pours starching the technique to be living inner place the embankment of the Weihe River , Design requirement can take shape accords with , The plumb successive thick liquid part of the body is provideed against seeing the heavy curtain , Osmosis damage when guarding against the embankment to be living the tall water level ; Being livingmoreover handle the embankment hole in a utensil Hidden danger such as split and loose double layer and so on respect effect is also very marked.Besides , Carry out by means of this , Also feeld about out some is fit for the embankment in Weihe River and chops to crack technique parameter and the economic target that the pouing thick liquid was builded , It is vast in the interest of our province to measure great One kind of fresh method and means is consolidated suppling except for a narrow pass to the not deep embankment project of blind water.更多还原
