2 . the design of cement power-sprayed is introduced in the thesis including composite foundation bearing capacity design, the checking computations of underlayer strength and composite foundation deformation 介绍了粉喷桩设计,即粉喷桩复合地基的承载力的设计计算,下卧层强度和复合地基变形验算,并对粉喷桩的设计思路作了归纳。
suspender is the most important bearing member in cfst arch bridge . their tension not only applies in design checking computation of suspender inner force but also is external force during calculating inner force of arch rib 作为钢管混凝土拱桥中重要受力构件-吊索(杆),吊索(杆)内力既可以用于吊索(杆)内力设计验算,也可以作为拱肋内力计算时的外荷载。
checking computations of stability of slope is the key of design of slope by the highway, if you want to improve stability of the slope by the highway designed . primary problem is choose suitable analysis method and fetch rational parameter 边坡稳定性验算是公路边坡设计的关键,要提高所设计公路边坡的稳定性,首要问题是选择适宜的分析方法和参数的合理取值。
thus it is added that we study machining technique, calculate, demonstrability and design for driveling system, and go along compare of experiment . based on testing, we have achieved many checking computations and improving, the testing answer for expectation finally 着重对加工技术进行了研究,对其传动机构进行计算、论证和设计,并进行对比试验,在试验的基础上进行多次验算和修正,最后试验结果基本达到了预期的效果。
due to the contribution of matrix suction to the shear strength of rock mass and the harmful function of temporary additional water load are considered, the checking computation result of the above mentioned method conforms to reality better than those of the previous methods 该程序考虑了非饱和带基质吸力对岩体抗剪强度的贡献以及暂态附加水荷载的不利作用(若具备含水量与岩体强度指标之间的关系,还能考虑水对岩体的软化作用),使计算结果更贴近实际。
