黑龙江张广才岭西麓野猪种群数量与危害调查及管理对策

野生动物学报, 2010
近年来,随着黑龙江省采取收缴狩猎工具、全面禁猎等有效的野生动物保护措施以来,全省大多数野生动物的种群数量得到了不同程度的恢复或增加,野生动物危害农作物事件不断发生,尤其是野猪侵害农田,给当地居民造成了经济损失。鉴于此,我们于2008年秋冬两季,对黑龙江省张广才岭西麓的尚志、五常两市7个林场进行了野猪数量和野猪危害情况的调查,分析了该地区野猪的资源状况,并提出了相关的管理建议,以期为有关林业部门的管理提供基础资料。

基于节点损伤的钢管混凝土平面框架火灾下破坏机理分析

Jianzhu Gangjiegou Jinzhan
本文以带钢筋混凝土楼板、采用外环板连接节点的三层三跨圆钢管混凝土（concrete filled steel tube，CFST）柱-钢梁平面框架为研究对象，从节点损伤角度对该类平面框架在火灾下的破坏机理展开研究。文中建立了足尺三层三跨CFST平面框架的耐火极限精细化有限元模型，并用相关试验数据验证了建模方法的准确性；基于底层受火危害大于高层受火危害、边柱受火危害大于中柱受火危害的原则，确定了12种典型的火灾工况，深入分析了不同火灾工况下CFST平面框架的破坏形式、温度变化、变形发展和内力变化。研究发现：
