砂砾石地基灌浆砂砾石地基灌浆sand-gravel foundation grouting shollsh一d!J一gLJonl旧rlg砂砾石地基灌浆(sand一gravel foundationgrouting)对砂砾石地基进行处理的灌浆。在砂砾石地基中进行灌浆，其主要目的是建造防渗帷幕。一般有两种情况，一是用于临时性工程，例如围瑶地基防渗;另一是用于永久性工程，例如大坝地基的防渗帷幕，它必须与大坝自身的防渗体紧密相连。 在砂砾石地基上建坝.坝基防渗采用灌浆帷幕方法的主要优点是:帷幕对地基变形的适应性好，施工中灵活性大，尤其适用于深厚砂砾石层的坝基防渗处理。在砂砾石层进行灌浆，必须查清地质情况，例如:砂砾石层的组成和分布，其中有无猫土和砂的夹层，夹层厚度如何;砂砾石层的渗透性;砂砾石层的颗粒级配等。 针对某种固粒浆液而言，其对砂砾石层是否可灌，一般常依可灌比值(M)而定.通常以下式表示 M=D巧/d:5式中D15为受灌砂砾石层的顺粒级配曲线上含量为15%处的粒径，mm.姚5为灌注材料的颗粒级配曲线上含t为85%处的粒径，mm。通常认为M>10~15，即表示可以灌注。 在进行坝基帷幕灌策设计之前，应先进行现场灌浆试脸，以试验所得的成果，作为设计的主要依据。 帷幕的型式有均厚式和阶梯式两种。前者帷幕厚度相同，也就是各排灌浆孔的深度相同，多用于较浅的砂砾石层;后者帷幕厚度不同，上部排数多，下部排数逐渐减少，呈上宽下窄的阶梯状，多用于深厚的砂砾石层。 帷幕的深度，一般要求穿过砂砾石层进人基岩。阶梯式帷幕中一般均有1一3排孔进人基岩。 砂砾石层灌浆一般采用水泥猫土浆。水泥与猫土的重t比为1:1~1:4.干料与水的重量比(浆液浓度)为l:1~1:3。浆液结石28天强度要求达到5X 10‘Pa。 选用猫土的条件一般为:塑性指数10%一20%;顺粒(<0.005 mm)含量不少于40%~50%;颖粒(0.005~0.05 mm)含t不多于45%~50%;含砂量小于5%，有机物含量小于3%。 常用的灌浆方法有4种:①打管溜浆法，②套管灌浆法，③循环钻灌法;④预埋花管法。 钻孔的方法依使用的灌浆方法和砂砾石层组成状况而定，可以采用冲击式钻进，也可采用旋回式钻进。当采用前述③和④两种灌浆方法时，允许使用泥浆。 帷幕灌浆完毕后，钻检查孔，做注水或压水试验，求得渗透系数，检验其是否满足设计要求。 通过工程实践，在砂砾石层中使用水泥猫土浆进行灌注，渗透系数可以降低到10--‘一10一”cm/s，若欲再行降低，一般需加用化学灌策.
