学习在 grouting 效果和 grouting 因素之间的关系，沙的石子上的无方向的压力和小周期 grouting 模型实验被做的三个因素(七个参数) 它根据制服被设计设计方法。并且 regressing 被用于测试数据的分析。当薄泥浆的扩散半径从 26 ～ 51 厘米变化时，二模型测试结果显示那，沙的石子压缩力量从 2.13 ～ 12.30 MPa 改变的 grouted；在传播半径(R) 和水水泥比率(m) 之间的关系，渗透系数(k) ， grouting 压力(p) ， grouting 时间(t) 是 R=19.953m 0.121 k 0.429 p 0.412 t 0.437；在压缩力量(P) 和孔(n) 之间的关系，水水泥比率， grouting 压力， grouting 时间是 P=0.984n 0.517 m 1.488 p 0.118 t 0.031。那么沙的石子的孔，沙的石子的渗透系数， grouting 压力， grouting 时间，水水泥比率是主要因素影响 grouting 效果。grouting 压力是主要因素影响传播半径的 grouting，并且水水泥比率是主要因素影响 grouted 沙的石子压缩力量。

英文摘要：

To study the relationship between grouting effect and grouting factors, three factors （seven parameters） directionless pressure and small cycle grouting model experiment on sandy gravel was done, which was designed according to uniform design method. And regressing was applied to analysis of the test data. The two models test results indicate that when the diffusing radius of grout changes from 26 to 51 cm, the grouted sandy gravel compressing strength changes from 2.13 to 12.30 MPa; the relationship between diffusing radius（R） and water cement ratio（m）, permeability coefficient（k）, grouting pressure（p）, grouting time（t） is R=19.953m^0.121k^0.429p^0.412t^0.437; the relationship between compressing strength（P） and porosity（n）, water cement ratio, grouting pressure, grouting time is P =0.984n^0.517m6-1.488p^0.118t^0.031. So the porosity of sandy gravel, the permeability coefficient of sandy gravel, grouting pressure, grouting time, water cement ratio are main factors to influence the grouting effect. The grouting pressure is the main factor to influence grouting diffusing radius, and the water cement ratio is the main factor to influence grouted sandy gravel compressing strength.
