摘要: 在同等条件下,用0.6 kg和1.8 kg的TNT药块对体积含量2.15%的钢丝网增强高强混凝土(HSC)试件和体积含量3%和5%的钢纤维增强HSC试件进行接触爆炸试验,并将试验结果进行比较。结果表明,体积含量2.15%的钢丝网增强HSC试件抗爆性能介于体积含量3%、5%的钢纤维增强HSC试件之间,抗爆性能具有优势,但优势略逊于抗侵彻性能。基于试验结果的综合分析,利用钢丝网HSC进行防护工程的抗爆结构设计时,其ka值可取为0.054.在同等条件下,用0.6 kg和1.8 kg的TNT药块对体积含量2.15%的钢丝网增强高强混凝土(HSC)试件和体积含量3%和5%的钢纤维增强HSC试件进行接触爆炸试验,并将试验结果进行比较。结果表明,体积含量2.15%的钢丝网增强HSC试件抗爆性能介于体积含量3%、5%的钢纤维增强HSC试件之间,抗爆性能具有优势,但优势略逊于抗侵彻性能。基于试验结果的综合分析,利用钢丝网HSC进行防护工程的抗爆结构设计时,其ka值可取为0.054.

Abstract: 0.6 kg and 1.8 kg TNT blocks are used to make the contact explosion tests for the steel-wire-net reinforced concrete sample which contains 2.15% steel and the steel fiber reinforced concrete samples which contain 3% and 5% steel under the same conditions, and the test results were compared. The results show that the anti-explosion capacity of the sample with 2.15% volume content is superior to that of sample with 3% volume content but inferior to that of sample with 5% volume content. The steel-wire-net reinforced concrete has some advantages in anti-explosion capacity, which is slightly inferior to the advantage of penetration performance. It can be found from the comprehensive analysis of the test results that the value should be 0.054 for the anti-explosion structures using steel-wire-mesh reinforced concrete.

Key words: mechanics of explosion, steel-wire-net reinforced, high strength concrete, anti-explosion performance, contact explosion
