摘要

西北盐渍土地区既有干线铁路受极端气候影响，路基出现上拱、融沉、强度降低等工程病害，且运营期无法采用换填等处治措施，因此亟需探明一种快速固结且能满足长周期服役需求的注浆浆液。依托西北某I级干线铁路，以粗颗粒硫酸盐渍土路基为研究对象，通过控盐效果、初凝时间及结石体强度试验确定最优配比后，进一步借助高低温试验箱、万能试验机等开展注浆固化土的冻融循环试验、强度试验、渗透试验及微观试验，揭示复合浆液及冻融循环条件对固化土性能的影响规律。试验结果表明：水泥的控盐效果优于粉煤灰，不同双浆液体积比下1%～3%缓凝剂能够使初凝时间延长至2～10倍，双浆液体积比为1∶0.5时结石体强度最高；最优配比浆液的控盐效果超过80%，初凝时间在2～10 min可调节，28 d抗压强度达到21.3 MPa；在8次冻融循环中，注浆后试样出现的最大变形量仅为注浆前的44.9%～61.2%，最大盐胀率均控制在1.08%以内；固化土在经历8次冻融循环后无侧限抗压强度仍满足规范要求(

≥250 kPa)，渗透系数回升幅度在63.6%～292%之间，最大为1.4×10

-5

cm/s；SEM观测显示，冻融作用下固化土的结构劣化低盐组以胶结网络断裂为主，高盐组形成“盐桥-裂隙”复合结构。研发结果可为同类铁路工程的注浆材料选型、病害治理方案制定提供重要的理论依据与实践参考。

Abstract

The existing trunk railway in the saline soil area of Northwest China is affected by extreme climate

and the subgrade has engineering diseases such as upwarp

thaw settlement and strength reduction. The treatment measures such as replacement cannot be adopted during the operation period. Therefore

it is urgent

to find out a grouting slurry that can quickly consolidate and meet the needs of long-term service. Based on a Class I trunk railway in Northwest China

the coarse-grained sulfate saline soil subgrade was taken as the research object. After determining the optimal ratio through salt control effect

initial setting time and stone body strength test

the freeze-thaw cycle test

strength test

permeability test and microscopic test of grouting solidified soil were further carried out by means of high and low temperature test chamber and universal testing machine

so as to reveal the influence of composite slurry and freeze-thaw cycle conditions on the properties of solidified soil. The results show that the salt control effect of cement is better than that of fly ash. Under different double slurry volume ratios

1%～3% retarder can prolong the initial setting time to 2～10 times. The stone body strength is the highest when the double slurry volume ratio is 1∶0.5. The salt control effect of the optimal ratio slurry is more than 80%

the initial setting time can be adjusted in 2～10 min

and the compressive strength of 28 d reaches 21.3 MPa. In 8 freeze-thaw cycles

the maximum deformation of the sample after grouting is only 44.9%～61.2% of that before grouting. The maximum salt expansion rate is controlled within 1.08 %. After 8 freeze-thaw cycles

the unconfined compressive strength of the solidified soil still meets the specification requirements (

≥250 kPa)

and the permeability coefficient rebounds between 63.6% and 292%

with a maximum of 1.4×10

-5

cm/s. SEM observation reveals that the structural deterioration characteristic of solidified soil under freeze-thaw action. The low-salt group is dominated by cementation network fracture

and the high-salt group forms a ‘salt bridge-fracture’ composite structure. The research results can provide important theoretical basis and practical reference for the selection of grouting materials and the formulation of disease treatment schem

es for similar railway projects.
