深埋高应力隧洞建设过程中潜在岩爆、片帮、塌方等工程灾害。中国锦屏地下实验室二期(CJPL-II)是目前世界上埋深最大的实验室(2 400 m),在隧洞群建设过程中开展了变形、应力、微震等系统的综合原位监测和力学响应数值模拟,该文系统分析了隧洞灾变特征与长期原位力学响应,研究结果表明:隧洞围岩变形以1#实验室和4#实验室北侧边墙较大,最大变形达83.7 mm,岩体锚杆应力最大为530 MPa,开挖完成后3个月,岩体变形趋于稳定;基于岩体声波和钻孔摄像揭示的围岩松弛深度范围总体约为0.8~3.5 m;围岩随开挖内部破裂演化,存在分区现象,强度较高且完整的岩体,破裂区范围较小,强度较低且完整性较差的岩体,破裂区范围较大;各实验室开挖时的微震在完整岩体隧洞和断层附近区域更为活跃,各隧洞强弱顺序依次为:8#、7#、4#、3#、5#、6#、1#、2#、9#,已完成开挖后的各洞室微震活动性逐渐趋于平静;基于CASRock软件分析表明:实验室开挖卸荷后南侧拱肩和边墙应力高、松弛深度较大,是高风险区。研究成果为实验室灾害预警、稳定性评估、动态设计及长期安全运营提供了直接支撑,也将为相似地质条件的高应力深埋隧洞安全建设提供借鉴。

The purpose is to study the effect of AdCMV-p53 gene transfer induced by radiation on cell cycles of human colorectal adenocarcinoma cells (HT-29). HT-29 cells were irradiated by 0. 5, 1.0,2.0 Gy 60Coγ-ray, then infected with AdCMV-GFP (a replication deficient recombinant adenoviral vector containing a CMV promoter and green fluorescent protein) or AdCMV-p53 (a replication deficient recombinant adenovi-

The purpose is to investigate the effect of 60Co y-ray irradiation on human prostate carcinoma cell infected with AdCMV-p53 and possible molecular mechanism. Human prostate adenocarcinoma cell line (PC-3 cells with mutations of p53), and recombinant adenoviral vector containing a CMV promoter and carrying human wild-type p53 gene (Ad-CMV-p53) were used in this study. The cells were pre-irradiated with 60Coγ-ray (0,0. 5, 1. 0 or 2. 0 Gy) and then infected with 20, or 40 MOI (multiplicity of infection)
