The construction of subways in Beijing was linked from the very beginning with war preparation and great importance was attached to the views from the military with respect to the line layout, the depth of burying, etc. 北京地铁的建设一开始就与战备连在了一起,在线路方案和埋设深度等方面,军方的意见受到重视。
Proposing a rational burying depth of reinforced concrete thin anchor wall body and putting forward that the performance of retaining wall will not improve even increasing the burying depth of the wall body if the rational burying depth is excessed. 提出钢筋混凝土薄壁锚拉墙存在合理墙体埋深,当超过此范围后,增加墙体埋深将不能改善挡墙的使用性能。
The bearing capacity is the crucial warranty to ensure the basic plane size and the depth of burying and placing. Ensuring the capacity rationally is the primary content of the geotechnical Investigation and foundation design. 地基承载力是确定基础平面尺寸和埋置深度的重要依据,合理确定地基承载力是工程勘察和地基设计的主要内容。
According to theory of bent structure, the paper applies the moment balance and potential energy theory, and works out the modified modulus 1 and 2 for the depth of burying foundation and toft transmutation, which effect buildings dynamic period. 根据排架结构分析理论,应用力矩平衡及势能原理分别推导出地基变形及基础埋深对结构自振周期的修正系数ζ1和ζ2。
According to influencing depth of foundation ground additional stress and influencing scope of deuterogenous stress of cave under foundation, the author classifies the cavern foundation into three types, that is, deep burying cavern foundation, shallow burying cavern foundation and cavern foundation without influence of cavern. 根据建筑地基附加应力的影响深度及地基洞室次生应力的影响范围,将岩石洞室地基分为深埋洞室地基、浅埋洞室地基和洞室无影响地基三大类。
The depth of pipes buried was from shallow to deep. The law of water seeping showed the same tendency. According to the law of wheat development requirement of water, 20 cm of burying depth was optimal. 渗灌埋管深度由浅到深,水分下渗规律也呈同样趋势,根据小麦发育需水规律,以埋深20cm较为理想。
The Problem on Frost Depth of Soil and Shallow Burying of Foundation 关于土的冻深与基础浅埋问题
The influence of the pile length is related to the burying depth of tunnel, while the ratio of pile length and burying depth being 1, the displacement reaches the maximum. 桩长的影响与隧道的埋深有关,当桩长与隧道埋深的比值为1时,隧道的位移最大。
