The first debate on coast defense of the late qing dynasty and its effect on the coast defense of our country 晚清第一次海防籌議對我國海防建設的影響
Up till now , considerable research on coast resorts mainly deals with the evaluation of tourist resources . however the research on tourist flows and local residents " perception of tourist impacts in coast resorts is relatively limited 目前國內關于海濱旅游地的研究主要集中在旅游資源評價方面,有關旅游客流和居民感知的研究成果不多。
Non - uniformity of the amplifying effect and dimension of the slope are pointed out through analysis of the distribution of the stress and sonic speed in the slope . forms of slope lost stability resulted from blasting vibration are analyzed and appraising rules of slope stability are summarized by a great deal instances on coasts . based on general discussion about calculation methods of the slope stability under the effect of blasting vibration , the synthetical method , a new one , is put forward , analyzed through a sample by and pointed out which is one of most valid methods 利用波動理論,得出延期時間為nt / m時減震效果最好;在分析邊坡巖體內部應力、質點速度等分布規律的基礎上,指出邊坡震動放大效應的不均勻性和邊坡尺寸效應;結合大量滑坡實例,分析了爆破震動引起邊坡失穩破壞的幾種形式,總結出邊坡穩定性評價準則;基于對邊坡穩定性計算方法的綜合分析,提出了一種綜合分析方法,通過算例計算分析,證明該法計算精確度高、功能全面,是邊坡動力穩定性分析的有效方法之一。
