筑坝

The analytical solutions of additional stress can be achieved by integrating the foundational pressure equations; and the solutions can are suitable for different dam materials, bedrocks and heights by setting some parameters.

解析公式中设置了几个参数使其适用于不同的筑坝材料和地基岩体，以及不同坝高情况的应力计算。

The damming technique is relatively perfect now, but because of the problems in construction management are more and more severe, such as construction scheme and matching machine, which manifest the high construction expenses.

虽然碾压混凝土筑坝技术已达到较成熟的地步，但是由于采用不同施工组织方案和机械配套方面存在的施工管理问题越来越突出，这集中反映了碾压混凝土坝施工费用的巨大浪费。

It is concluded that because the mica schist is mixed with feeble weathered granite, the grain is broken up severely; the back-analysis parameters of explosion rockfill(3BⅠ)are lower than the results of laboratory triaxial test, and the Duncan E-B parameters obtained by back-analysis of her sandy gravel (3BⅡ)are higher than the triaxial test results of laboratory triaxial test which can not reflect the mechanical behaviors of the dam material objectively; the research should be strengthened in 300 m high rockfill dam construction. The fitting modes of the space displacement field of prototype observation are also explored and it turns out that the results of IGA analysis considering only vertical deformation meet the need of dam's technical accuracy.

结果表明，由于在微弱风化花岗岩掺加云母片岩，颗粒破碎严重，爆破堆石料（3BⅠ）的原级配粗粒料反演参数远低于室内三轴试验成果；与3BⅠ堆石料相反，砂砾料（3BⅡ）现场反演得到的邓肯E~B模型参数高于室内三轴试验值；室内三轴试验成果不能客观反映筑坝材料的力学特性，对于当今的300 m级高土石坝建设，宜加强对原级配粗粒料的力学特性研究；同时对原型实测的空间位移场不同拟合方式进行了探讨，认为仅考虑铅直向变形的IGA参数反演成果能基本满足土石坝工程的精度要求。

The project includs the construction of channel dredging, dam wharf, tourist facilitiessuch as boat and yacht0, national reception center and camp holiday village.

该项目建设内容主要河道疏浚、筑坝、修筑码头、修筑民族接待站、野营度假村和购置游船、游艇等旅游设施。

In the construction of dams and cofferdams, and in the excavation of canals and others by means of directional explosions, it is always necessary to estimate the piling hape and the location of the soil or rock materials that have been thrown out by blasting.

在用定向抛掷爆破法筑坝、修围堰、开挖渠道及其他工程中，常需在爆破前估计爆破后土石方的抛掷堆积形状和位置。

It founds natural heightening theory for warping dams and puts forward specific way of diversion, measures for preventing dam eroded and design for energy dissipation and flood storage of cofferdams and sedimentation and dewatering through exploration and study on deposition in front of natural formed dam and the techniques of building dam through hydraulic filling....

通过对天然聚湫坝体前的淤积和&水力冲填&筑坝技术的探索和研究，创立了淤地坝坝体自然加高的理论，并提出了具体的导流方式、坝体防冲措施及围堰消能蓄洪、留淤脱水设计。建议尽快立项开展坝体自然加高现场试验和模拟试验。

The island rises from Lake Gatun, which formed in 1907 when the Chagres River was dammed during construction of the canal.

这座岛在Gatun湖中，而该湖是在1907年的运河工程中因对Chagres河筑坝形成的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
