长期浸水后衬砌材料抗压强度实验研究

Experiment Research to Compressive Resistance of Explosive Lining after Long-term Immersion

通过实验室实验,对爆炸衬砌试件、人工拌合的标准养护试件(以下简称"标准养护")和同等条件养护试件(以下简称"同等条件养护")长期浸水后的单轴抗压强度(以下简称"抗压强度")及长期浸水烘干后的抗压强度进行试验研究。结果表明:长期浸泡的爆破衬砌试件抗压强度16.06 MPa,比浸泡前下降11.22%,且小于标准养护和同等条件养护试件的抗压强度;经烘干后,爆炸衬砌试件抗压强度的平均值提高了25.59%。

Through laboratory experiments, the explosive lining test, artificial mixing standard curing test pieces（hereinafter referred to as ＂curing＂） and the same condition curing specimens（hereinafter referred to as ＂the same condition curing＂） after long-term immersion of uniaxial compressive strength（hereinafter referred to as the compressive strength） and long-term soaking and drying of compressive strength was studied. The results show that the compressive strength of 16.06 MPa, which is a long time immersion,is decreased by 11.22%, and the compressive strength of the specimen is smaller than that of the standard curing and the same condition. After drying, the average value of the compressive strength of explosive lining is increased by 25.59%.
