5 . some important dynamic responsive parameters are worked out about the reinforced earth structure under the impelling loads of train by model tests and analysis of dynamic characteristics 5 、通过对铁路加筋土挡墙在列车重复荷载作用下的室内模型试验和动力特性分析,得出了加筋土挡培在动力荷载作用下的一些重要动态响应参数。
Research of the dynamic characteristics of reinforced earth structure has become a resistless important task when the express highway and express railway are built and the reinforced earth retaining walls are widely applied 然而,随着公路、铁路的提速及加筋土挡土结构的应用领域的拓宽,对加筋土挡上结构进行动力方在的研究已成为一个不可回避的重要课题。
The jiangcang mining area locates the position of special earth structure , regional structure developed distinguishingly , with the third kind of structure complicated degree and the third type of coal bed stable degree and metamorphic grade 摘要江仓矿区位于特殊的大地构造位置,区域构造演化特殊,构造复杂程度属三类,煤层稳定程度和煤质变化程度属三型。
( 2 ) the lateral deformation is effectively limited by reinforced earth layers and the settlement becomes small . @ the lateral deformation is enlarged on soft foundations , and the settlement becomes large . @ the reinforced earth layers on soft foundations behaves extension . the response behaviors of high sand - gravel embankment are indicated as the following : ? he amplification factor of earthquake acceleration varies with reinforced earth structure . ( 2 ) the basic frequency of the original embankments in different reinforcement conditions is about 0 . 76hz . ? the amplitude of dynamic deformation appears small and the dynamic stability is safe 研究表明:加筋土体能有效地限制路堤的侧向位移发展,减小沉降变形量;软基路堤的侧向位移较大,将显著地增大路堤的沉降变形;软基上加筋土垫层中产生的拉应力最大;加筋砂砾土路堤在振动荷载作用下动变形反应较小,具有良好地动力稳定性。
The topic of this paper is structure , firstly analyse the earth structure setting of tarim basin and tectonic evolution of tazhong area in silurian - devonian , and give silurian - devonian stratum control and effect , then study the relationship of the development of tazhong uplift , fracture unconformity igneous rock and and oil - gas , at last , on the base of the analyse about history of reservoirs formation , forecast reservoirs pattern , point out favored oil and gas bearing structure and the target . and obtain some important conclusion . 1 本文以构造研究为主题,详细的分析了塔里木盆地志留泥盆系沉积时的大地构造背景和塔中地区的构造发展,以及它们对研究区志留?泥盆系地层的控制和影响,同时在研究了塔中隆起的形成发展演化、断裂、不整合以及火成岩等构造特征的基础上,分析了它们与油气的关系,结合志留泥盆系突破井的成藏史分析,预测了成藏模式,最后指出有利含油气构造,并进行了简单的目标预测。
