This article gives an example by describing the construction of a wharf along dense breccia-tuff shore with a slope of 35-40 degrees.This wh...             预裂爆破具有形成光面、保护岩壁和减轻地震波等作用,用来建造码头还可以不必筑堰排水,爆破形成的岩壁可不加衬砌,直接供船舶停靠,因而具有很高的经济效益。本文叙述在坡度呈35～40°的致密角砾凝灰岩海岸上,建造一座岸壁码头的实例。码头具有结构简单,造价低和施工机具简单的优点。具有重力式所不可比拟的耐久性、承载力、抗震性、抗风浪、抗冲击,抗爆炸的能力。这对于建造外海和沿岸岛屿码头尤为重要。水下预裂爆破,同样适宜在江、河、湖、海建造水下洞库、岩基船坞、坞口导航墙,升船机的升船槽,船闸闸室等,具有广阔的发展前景。 文摘来源          Various simplified mechanical models of Yong-River Bridge are set up in this paper. The nonlinear earthquake response analysis of the bridge has been made according to the 1976 Tianjin records, the 1940 E1-Centro records and the artificial seismic wave inputed respectively by using the analysis programs ERAB(Earthquake Response Analysis Programs for Bridge). Finally, based on the above analysis a preliminary strengthening plan for the bridge has been proposed.             本文对邕江大桥给出了各种不同的动力计算模型,取用天津波、El-centro波和人工地震波分别对该桥进行非线性地震反应分析。在分析的基础上,提出该桥的加固建议方案。 文摘来源          Based on the computer calculation results of the transfer matrix method, this paper gives a quadratic regression formula for the first natural circular frequency of piers of various sections on rigid foundation. By adding 14 samples in the statistic analysis, another formula has been obtained, improving the original linear formula. This paper also presents two quadratic regression formulas for the first natural circular frequency for piers on shallow foundation and caisson foundation respectively, in which ...             本文以转移矩阵法电算结果为基础,在补充了14个子样后,除对原刚性地基桥墩第一自振圆频率ω_1的直线回归公式修正为曲线回归公式外,并分别提出了考虑地基弹性变形影响后,浅平基桥墩和沉井基础桥墩的曲线回归公式。此外,还提出了考虑地基弹性变形后用抗震设计反应谱进行计算的墩底剪力系q_0和弯矩系数m_0的公式。这些公式简单,精度能满足工程需要。 文摘来源   << 更多相关文摘         相关查询: seismic mass seismic level seismic multiples vibration seismic seismic scientific seismic requirements seismic reflectivity seismic clusters seismic groove exploration seismic design seismic seismic amplifiers  对查询结果不满意
