浆液浓度的正确选用与合理变换,关系着灌浆进展的快慢与质量之优劣,至今仍处于试验和探讨阶段,但前景可观,不少单位和学者都进行过专门研究并在理论上有所阐述。我们结合老营盘水库大坝基础帷幕灌浆试验结果,作如下探讨。由于岩石受到不同的地质营力(构造作用力和地质外营力),故其裂隙在几何形态上也就不同,裂隙的发育程度和分布状况也不相同,因而导致岩层的透水性及浆液对其可灌性也千差万别。
The correct selection and rational change of slurry concentration is related to the quality and the progress of the grouting. It is still in the stage of experiment and exploration, but the prospect is considerable. Many units and scholars have conducted special studies and elaborated in theory . We combine Laoyingba dam foundation curtain grouting test results for the following discussion. Because rocks are subjected to different geologic forces (tectonic forces and geologic forces), their fractures are geometrically different, and their fractures have different degrees of development and distribution, leading to water permeability of the rock formations and to slurry Its irrigation ability varies widely.
