用厂坝连接解决大坝深层抗滑稳定问题

本文以万家寨水电站为背景，研究了不同厂坝连接方式对坝体和厂房的应力、变形及深层抗滑稳定性的影响。研究结果表明，考虑混凝土重力坝与坝后式厂房的相互作用后，可以提高大坝抗滑稳定性，改善坝体应力状态，并能减小由于下游尾水过高引起厂房向上游的变形。     

Shape up or ship out? Employment discrimination against the overweight

Increasing health care insurance costs have focused employer attention on health-related factors in employee recruitment and retention. One such factor is weight. Employers have argued that overweight employees are absent more often, are more susceptible to on-the-job injuries and illnesses, and are less productive than others. They have also contended that overweight employees present poor role models and may cause “negative reactions” by others. Although no federal law addresses employee obesity specifically, a number of laws prohibiting other forms of discrimination present potentially litigious situations. This article reviews the background and legal framework of discrimination against the overweight and offers some guidelines for avoiding such charges.

Reducing crimes against wildlife through promoting animal–human continuity beliefs: The role of consumers' religiosity

Wildlife crime is a worldwide issue, but marketing research has been mostly silent on the topic. In particular, research has yet to understand how a consumer's level of religiosity may help to explain views toward and participation in crimes against wildlife. Thus, through three studies, these challenges are addressed. Study 1 shows that religiosity positively influences acceptability views and participation in crimes against wildlife, and this relationship is mediated by animal–human continuity beliefs (i.e., believing animals and humans are one of the same). Study 2 primes religion to show that religiously primed consumers are more likely to view crimes against wildlife as acceptable, thereby supporting religiosity as a primary mechanism in explaining crimes against wildlife. Additionally, animal–human continuity beliefs again mediate this relationship, with religiously primed consumers reporting lower animal–human continuity beliefs. Lastly, Study 3 provides practical implications through marketing messaging aimed at reducing attitudes toward and participation in crimes against wildlife. Findings reveal that religious-based messaging is the most effective. Findings build on belief congruence theory and provide implications for marketing practice and the preservation of wildlife.

边坡稳定极限分析斜条分上限法的全局优化方法

边坡稳定极限分析斜条分上限法需要寻求最小安全系数对应的临界滑动模式。由于待优化变量中包含了滑裂面位置与条块界面倾角,问题的自由度与非线性程度明显增加,寻找安全系数的整体极值变得十分困难。本文建立了任意形状滑裂面通过与不通过软弱夹层两种情况下斜条分上限法滑动模式优化的数学模型。为保证在随机搜索过程中生成合理的滑动模式,引入一系列约束条件,将临界滑动模式的搜索问题转化为一个有界约束的数学极小值问题,并结合遗传算法和粒子群算法两种全局优化方法,对多个典型算例进行对比分析。研究表明,提出的模型可以解决优化过程中生成不合理滑动模式的问题,不仅极大地提高了优化效率,而且可以避免数值计算不收敛的麻烦;将模型与全局优化算法相结合,在大多数情况下能够得到一个合理的、与极限平衡解十分接近的上限解,具有较好的全局收敛性。     

Kokhav Hayarden抽水蓄能电站上、下库坝坡抗震稳定分析

参考国际水电工程的相关要求对以色列Kokhav Hayarden抽水蓄能电站上、下库坝坡进行抗震稳定分析。采用以色列英文版抗震设计规范SI 413—2013确定深厚覆盖层上坝体建基面加速度反应的峰值、加速度设计反应谱和时程输入加速度,进而采用美国规范ASCE 7-05和ICOLD等建议的三种常用拟静力法和拟动力法(Newmark滑块位移法)对建立在深厚覆盖层上的上、下库坝坡进行运行地震和最大设计地震下的抗震安全性复核。由不同允许滑动位移下的拟静力安全系数和坝坡地震滑动位移量计算结果可知,Kokhav Hayarden抽水蓄能电站上、下库坝坡均能满足OBE地震下坝坡位移小于5 cm的工程技术安全控制要求,坝坡抗震设计满足规范要求,上、下库坝坡在OBE和MDE地震下具备良好的抗震稳定性。研究成果对国际工程中深厚覆盖层上土石坝坝坡抗震设计和安全评价具有重要的参考价值。
