为研究微震荷载作用下注浆加固体力学特性,以裂隙倾角30°、宽度4 mm的红砂岩裂隙注浆体为研究对象,借助岩石三轴伺服压力机进行变应变速率(10^-5~5×10^-3 s^-1)单轴压缩试验;然后从能量耗散、裂纹扩展及破坏形态等3个方面,分析变应变速率对注浆体力学特性的影响规律及机理.研究表明:随着应变速率的增加,注浆体的峰值强度、弹性模量均随之而增大;且峰值强度与应变速率呈指数函数关系变化;注浆体受应变速率影响的响应分为敏感应变速率阶段和滞缓应变速率阶段,主要差异在于峰值强度变化率和弹性模量变化率;随着应变速率的增大,注浆体的总能量在增大;压密阶段是影响不同应变速率下注浆体力学特性的主要阶段;敏感应变速率阶段和滞缓应变率阶段中的压密阶段主要区别在于积散比大小,积散比进一步决定产生裂纹的多少和分布区域与规律;耗散能密度对注浆体破坏脱落面积以及粒径分布影响较大,耗散能密度越大,碎块越以大块为主(粒径大的比率逐渐增加),滞缓应变率阶段耗散能密度较敏感应变率阶段大,其破碎块体较敏感应变率阶段大.研究在裂隙注浆加固体的变应变速率影响下力学特性,从能理原理、分形理论角度得到了其影响机理.

预应力管道压浆浆液外加剂种类及配合比的选取是管道压浆工艺的重要部分。为研究减水剂和矿物掺和料对管道压浆浆液的影响及作用机理,进而研制一种流动性、保水性及力学性能优异的管道压浆浆液,本研究采用单组分掺和试验的方法,对掺有减水剂与矿物掺合料两种不同压浆浆料进行流动性、压力泌水率、沉积密度比、抗压及抗折性能试验研究,并得到不同掺量外加剂对压浆浆液和易性与力学性能的影响和作用机理,以及合适的外加剂掺量配比。研究表明:聚羧酸减水剂30 min与60 min流动度最佳,且压力泌水率表现也较为良好,综合考虑聚羧酸减水剂为压浆浆液的优良减水剂;聚羧酸减水剂掺量在0.4%~0.5%时,浆液的流动性与保水性表现良好,随掺量的继续增加,流动性提升较小;微珠由于其物理性质以及化学性质,对提高压浆浆液和易性与力学性能的效果较为明显;微珠掺量在10%~15%时,压浆浆液的和易性达到临界状态。
