摘要：针对长春岭水库大坝的渗漏特点,通过改进坝体劈裂灌浆的灌浆材料及施工工艺,对该水库大坝进行了防渗加固设计。工程施工完成后经历台风"圆规"及高水位考验,目前水库运行状况良好,并已通过工程验收。

摘要：This paper deals with the ef ects of salinity on the eggs and newlyhatched larvae of Mugil so-iuy. It was found that all the fertilized eggs were hatched out within the range of salinity 5‰-40‰, and the normal hatching rate was the highest at 35.6%. Moreover, the larvae hatched at salinity 35.6%0 were able to survive within the range of salinity 5.1‰-43.2‰. And the effect of salinity, on the length of the newly-hatched larvae was discussed.

摘要：采用袖阀管灌浆对川气东送穿越长江堤防工程管线周围土体进行加固处理,加固后堤防的密实度和防渗效果有了明显改善,消除了管线定向穿越给大堤防洪带来的隐患。

摘要：上海市机场联络线是国内首次在大直径盾构隧道中采用整体式预制弧形件的工程,而现阶段缺少对整体式预制弧形件选型及排版的研究。针对该问题,本文分析了标准环+左转弯环+右转弯环、左转弯环+右转弯环和通用楔形环三种管片形式下弧形件的构造设计,并给出排版计算方法。结果表明,在标准环+左转弯环+右转弯环和通用楔形环管片形式下,分别采用直线形+楔形弧形件和无楔形量的弧形件能较好满足工程需求,建议在类似工程中选用。
