宜万铁路别岩槽隧道F3断层突发性涌水治理

研究目的：宜万铁路别岩槽隧道F3断层围岩破碎，为碎石土，局部溶隙、溶槽发育，有少量地下水，施工中按V级围岩采用超前小导管支护、格栅钢架支撑、网喷混凝土，采取台阶法丌挖。在初期支护完成3个月后，由于受地表强降雨影响，致使隧道线路右侧暗河（距隧道约10-20m）水量增大、水压升高，继而导致隧道初期支护严重开裂-变形，突发大规模涌水。本文主要分析了F3断层突发性涌水机理，介绍了F3断层突涌水的治理措施。 研究方法：突发性涌水后，现场立即启动应急预案，在安全监视下，采取工字钢环向加固和横向支撑，并对线路右侧边墙进行钻孔放水泄压。水量稳定后，对F3断层段采取径向加固堵水注浆；拆除变形格栅钢架，采用120钢架替换；并及时施作二次衬砌。 研究结果：通过采取“径向注浆加固-初期支护加强-及时施作二次衬砌”等综合技术措施，F3断层治理后，仅在局部位置出现渗流水，水量1m^3／h，治理效果良好。 研究结论：（1）通过别岩槽隧道F3断层涌水事故，当隧道周围（不超过100m）存在暗河通道等赋水条件，隧道开挖揭示囤岩破碎，那么，既使隧道开挖中未发生涌水，也难以保证初期支护完成后不发生涌水事故，甚至很难保让隧道完成后运营过程中不出现问题，随着“强本简末，为运营服务”隧道修建理念的提高，针对类似地质构造，做到提前防范，加强处理。（2）针对类似别岩槽隧道F3断层地质特点，采取径向注浆是一种有效的治理及防范措施。

A modified reinforcement learning algorithm for solving coordinated signalized networks

This study proposes Reinforcement Learning (RL) based algorithm for finding optimum signal timings in Coordinated Signalized Networks (CSN) for fixed set of link flows. For this purpose, MOdified REinforcement Learning algorithm with TRANSYT-7F (MORELTRANS) model is proposed by way of combining RL algorithm and TRANSYT-7F. The modified RL differs from other RL algorithms since it takes advantage of the best solution obtained from the previous learning episode by generating a sub-environment at each learning episode as the same size of original environment. On the other hand, TRANSYT-7F traffic model is used in order to determine network performance index, namely disutility index. Numerical application is conducted on medium sized coordinated signalized road network. Results indicated that the MORELTRANS produced slightly better results than the GA in signal timing optimization in terms of objective function value while it outperformed than the HC. In order to show the capability of the proposed model for heavy demand condition, two cases in which link flows are increased by 20% and 50% with respect to the base case are considered. It is found that the MORELTRANS is able to reach good solutions for signal timing optimization even if demand became increased.     

Predicting the Dielectric Strength of c-C4F8 and SF6 Gas Mixtures by Monte Carlo Method

An improved Monte Carlo method was used to simulate the motion of electrons in c-C_4F_8 and SF_6 gas mixtures for pulsed townsend discharge. The electron swarm parameters such as effective ionization coefficient, [AKα-] and drift velocity over the E/N range from 280～700 Td(1Td=10-21 V·m2) were calculated by employing a set of cross sections available in literature. From the variation cure of [AKα-] with SF_6 partial pressure p, the limiting field (E/N)_lim of gas mixture at different gas content was determined. It is found that the limiting field of c-C_4F_8 and SF_6 gas mixture is higher than that of pure SF_6 at any SF_6 mixture ratio. Simulation results show excellent agreement with experiment data available in previous literature.

p16INK4/CDKN2在胆囊癌中的表达及临床意义

为明确p16基因及其产物在胆囊恶性肿瘤中表达的意义，用免疫组化ABC法对46例胆囊癌p16INK4／CDKN2表达进行检测，结果表明：p16INK4／CDKN2在良性病变中的阳性率高于胆囊癌（P＜0．05）。该蛋白的失活或缺失主要见于肿瘤的中、晚阶段，与胆囊外浸润和淋巴转移密切相关（P＜0．01），与肿瘤的病理类型及分化程度无关（P＞0．05）。检测p16INK4／CDKN2对临床正确地估计肿瘤的侵袭性、淋巴转移潜能及判断预后具有重要价值。
