文章尝试用周期性振动荷载代替冲击荷载,即采用振动排水固结法处理软土。借鉴振动采油,并结合动力排水固结法。设计将一定频率的机械波通过人工震源在地面上形成波动场,传递到一定深度范围内的土体上,然后再对土层进行大面积的震动和加固,使松软的土基在波动的作用下,推进固结过程的速度更快,效率更高。在不同地区,受矿物成分、沉积条件、物理和化学等因素影响,软土的含水率、扰动程度都不一样。所以有必要对不同土样的振动排水固结特性进行试验分析。

在建筑结构施工中,经常会有部分区域需要优先施工作为优展区进行开放的部分,对于这部分属于园林建设的工程,尤其要注意土体排水与沉降问题,但是,在某些情况下,如建筑区域处于既有结构种植屋面之上或其他需要将建筑结构连接至原有结构的,就需要对施工区域合理规划,选择最优选的路径和方法进行施工。在先施区域内一侧排水会污染施工现场或无法有效排水时,因此为避免雨期及平时土体水分无法有效排出从而影响员工施工安全和现场施工效率,采用在先施区域一侧沿挡土墙外侧按标准设计并修筑砌筑排水沟及保护固定设施 ...

Recognizing animal personhood in compassionate conservation
Abstract Compassionate conservation is based on the ethical position that actions taken to protect biodiversity should be guided by compassion for all sentient beings. Critics argue that there are 3 core reasons harming animals is acceptable in conservation programs: the primary purpose of conservation is biodiversity protection; conservation is ...
