| 摘 要： | 通过室内水泥浆液正交试验,优选出水泥灌浆锚杆的水泥外加剂类型及加量比例,以提高锚杆固结水泥结石体的早期强度,在确保水泥浆液的可灌性条件下,可使水泥 (2~3d)凝期的强度提高 50%~100%,即将锚杆张拉与锁定的时间缩短到 2~3d左右,确保边坡支护体系的安全性。

| Abstract: | In order to greatly enhance the primary conpres sive strength of cement grouting liquid used for anchor engineering ,through laboratory and ground tes ting,types and weights of cement's additive obtained optimizing. Under the condition that the cement slurry is groutable,the conpressive strength of cement groutin g liquid could increase 50 to 100 percent in two or three days condensing time, which would greatly enhance the construction speed of anchor engineering, timely control metamorphose of borderslope ,as to insure safety of supporting system . |
