Small standard products of king tensile tent can be divided into three types due to the structural systems : cable - column tent, internal lifting tent and external suspending tent, in which we prefer to recommend the cable - column tent for your choice on account of its lowest cost and shortest installation time
今騰盛小型單體蓬房按結構形式可以分為索柱結構形式內頂結構形式外掛結構形式，其中索柱結構形式經濟性最好，拆裝最快捷，是我公司的主推產品。2. the complex stiffness corresponding to three bearing conditions of semi - infinite elastic subgrade, finite elastic soil layer and end bearing at the pile bottom are theoretically investigated, and analytical expression of the complex stiffness corresponding to finite elastic soil layer bearing condition is obtained. the special influence of bearing conditions on dynamic response at pile head is then discussed
2 、對剛性支承、有限厚度土層支承和半無限空間支承三種樁底部支承情況下樁底支承復剛度和樁周土底分佈支承復剛度的解析表達及其特性進行了推導論證，通過假定樁底土為與樁等截面的土柱推導求得有限厚土層支承條件下樁底支承復剛度的解析解，並據此分析了不同底部支承邊界對樁頂響應的影響。Abstract : that the prevention measures are not enough at the prop - drawing operation in the stope is analysed at this paper, and the structure and the site application effect of dth push - protecter are introduced
文摘:分析了回採工作面回柱放頂作業中防護措施的不足，介紹了dth推護器的結構和現場應用效果。Then the formu1a of computing the maxima1 top shear stress in designing masonry bui1dings and the method of checking computations of cracks are brought forward in this paper on the basis of the theoretica1 deduce and the data of these tests and experiments. a1so, the practica1 construct methods and the requirements of preventing such cracks in the aspects of the construct rate. the strength and modulus of e1asticity of the masonry bui1dings are put forward
隨后，本文在理論推導和試驗數據的基礎上，提出了在砌體結構設計中計算頂層最大剪應力的公式和是否開裂的驗算方法，並且從施工進度、砌體的強度及彈性模量、構造柱和圈樑的設置等方面提出了防止此類裂縫開展的具體施工方法和要求。分享友人
