摘　　要：高压喷射灌浆技术凭借其成本低、速度快、可靠性高及防渗效果好等特点,在水利工程的堤基加固及水工建筑物防渗工程中被广泛应用。结合中亭河防护工程,基于钻孔原理,在地层复杂的部位及可能存在质量缺陷的部位对摆喷墙钻孔芯样的完整性、强度和渗透系数等进行检测,以此判断工程的防渗效果。由检测结果分析可知,所取芯样的各指标均符合要求,工程的实施达到了预期的防渗效果。H ig h pressure je t grouting technology is w id e ly used in w ater conservancy projects due to its low c o s t,h ig h spe ed,hig h re lia b ility and good seepage prevention e ffe ct.T h is a rtic le m a in ly through the pro je ct o f Zh ong ting R iv e r p ro te c tio n,based on the p rin c ip le o f b o re h o le,the in te g rity,strength and p e rm e a b ility co e fficie n t were tested in the com plicated parts o f the stratum and the parts th a t may have q u a lity defects.The test results show th a t the construction o f im pervious w a ll has achieved good re su lts.
