黄土在应力作用下迂水时力学强度迅速下降 ,产生大范围的快速沉陷。这就是黄土的湿陷性 ,是黄土的诸多特性之一。鉴于对黄土湿陷性以往用各种实验室试验指标进行评价 ,这里提出运用动力触探和静载荷试验进行黄土湿陷性原位评价的一种简便的新方法。该方法的试验程序是 ,先用轻便可变动能触探仪在天然状态和饱水状态下进行触探试验 ,而后在触探孔完成静载荷压缩性试验。运用中国黄土高原黄土原位动力触探和静载荷试验测得的资料 ,详细分析了天然状态的黄土对探头阻力 qdna.,饱水状态的黄土对探头阻力 qdsa.,实验室测得的湿陷性指数δs压缩曲线参数 (即触探极限压力 ppf,触探蠕变压力ppl 和触探载荷模量Epn)的关系。结果证明所提出的方法适用于原位判定黄土的湿陷性。

本文叙述了最近关于上地幔不均匀性的地震学证据。地震学家们在关于上地幔结构低阶球谐展开的看法正逐步趋于一致的同时,关于短和中等波长特征仍存在激烈的争议。局部地壳研究也证明了所有可分辨尺度范围内上地幔为非均匀的,全球模型低估了波速异常幅值。一些重要问题悬而未决:(1)消减板片的结局;(2)扩张中心下面的低速带深度范围;(3)热点产生的深度。近年来,通过对波形观测资料的分析,我们对上地幔总体径向分层有了更明确的认识。这些观测来自新一代宽频带数字地震台站以及空间上的高密度分布的窄频带地震台阵。然而,关于平均径向结构方面的重要问题仍然存在。大陆下面的低剪切波速带图象已很详细,Jorda. 构造圈假说已由区域一维和全球层析研究得到充分证实。但它不能清楚地显示出什么范围低剪切波速和低压缩速度匹配。各向异性,由于使人信服证据存在于剪切波分裂观测中,因此将对确定低速带形状起作用。在软流圈下部,大约220 km处存在的 Lehma.n 间断面作为全球特征是靠不住的,但520 km 处相交的早期显示已在地震波叠加截面中发现了一些证据。在现代消减带附近的较深部位已观测到低速异常带,甚至在古缝合带下方也曾观测到。目前地震波分析方面的进步由地震仪器的两种重要进展所带动:(1)全球宽频带地震台的安置;(2)地震台网中台站密度的增加。将来的进步将很可能依赖稠密地震台网的扩大,包括临时的和可移动式的台站;依赖我们增加海洋地区台站的覆盖能力和依赖于计算非均匀地球模型的波形正演问题提高到容许非线性最优化的有效水平。

For this purpose, a methodology of four main steps was applied. The methodology involved delineating a.>the a.>up-to-date reservoir using remotely sensed data, simulating reservoir at full capacity, estimating current and potential reservoir capacity and finally assessing environmental impacts of the reservoir. The results revealed that the up-to-date reservoir covers a total area of 330.3 km2 with a.>a a.>gross storage capacity of 12 billion m3. Under full capacity scenario, the reservoir is estimated to cover a total area of 1650.9 km2, with a.>a a.>storage capacity of 63.4 billion m3. a.>The a.>GERD reservoir may lead to dramatic changes in the local environment with significant implications at both regional and global scales. In this respect, it was found that the reservoir will lead to destruction of ecosystems in a total area of 1300 km2 covered by grasslands and Savannah.
