摘要: 为了研究交河故城保护灌浆加固材料，在不同水灰比PS-C浆液实际灌浆过程中，对不同裂隙的渗透能力及灌注效果做了初步探讨。在实验室模拟灌浆墙体的基础上，依据实际施工条件分别配置了不同水灰比的PS-C浆液，并对其灌浆过程中的灌浆压力及灌注效果进行检测，通过对检测数据的比较分析，得出了现场施工中不同裂隙宽度对浆液水灰比的选择依据。对大于1 cm宽度的裂隙应使用0.6水灰比的浆液；对介于0.75～1.0 cm的裂隙应使用0.65水灰比的浆液；当裂隙宽度在0.5～0.75 cm时应使用0.7水灰比的浆液，而当裂隙小于0.5 cm时应使用0.75水灰比的浆液。

Abstract: In order to study the influence of PS-C grout with different C/W ratios on its groutability to different fractures of Jiaohe ruins, the grouting pressure and effects are discussed. Based on the data of experiments, a conclusion is drawn that when the fracture width is larger than 1 cm, the grout with 0.6 C/W ratio should be used. When it is 0.75 cm to ~ 1 cm, the grout with 0.65 C/W ratio should be used. The grout with C/W ratio of 0.7 should be used when the fracture width is between 0.5 cm and 0.75 cm. When it is smaller than 0.5 cm, the grout with C/W ratio of 0.75 should be used.
