潮汐河口二维动床紊流模型

给出了正交曲线坐标系下平面二维非恒定动床紊流模型基本方程组,即水流运动方程及潮汐水流不平衡输沙方程。对计算中的有关问题提出了处理方法,如基本资料及代表潮过程选取、糙率的确定、悬沙粒径及沉速、挟沙能力恢复饱和系数及河床冲淤判别条件等。以甬江口为例,计算了镇海弯道至大游山口门约5km河段潮汐水流潮位及流速过程、丁坝作用下的回流域及疏浚与整治相结合的河床变形,计算结果与野外资料吻合良好。在此基础上,计算了宁波大桥桥墩作用下的水流结构变化及对镇海港航道的冲淤影响。     

影响断层带再活动的一些因素的实验研究

很多地震发生在活动断层上。但断层带是否活动并不是一成不变的。目前,在没有大量实测资料的情况下,我们往往还要推断哪些断层是易于活动的。实验与计算结果表明,影响断层再活动的因素为力的方向、力的大小,断层带厚度,断层带物质的力学性质等。这些结果将有助于我们推测活断层。

关于黄土碳酸盐与气候环境关系探讨

黄土中碳酸盐与气候环境密切相关。从碳酸盐的成因看，干冷的气候利于原生碳酸盐的保存，而温湿的气候使大量的次生碳酸盐产生。碳酸盐的存在形式与降水量多少有关，降水量大可形成结核层和钙板等，而降水量小则形成各种胶膜。胶膜中各种不同形态的方解石胶膜又可反映不同的气候条件。黄土一古土壤中形成的碳酸盐实际上在古土壤期形成的碳酸盐要高于黄土期形成的，只是由于古土壤期强烈的风化淋溶作用，大量的碳酸盐从古土壤中淀积到下伏的黄土层中。黄土中CaCO3的淀积可分为连续淀积和不连续淀积两类。依据淀积深度和降水量的关系，可建立二者定量的关系。从黄土碳酸盐的不同方面，得到其与气候环境关系较为全面的认识。     

A new solution for a partially penetrating constant‐rate pumping well with a finite‐thickness skin

A mathematical model describing the constant pumping is developed for a partially penetrating well in a heterogeneous aquifer system. The Laplace‐domain solution for the model is derived by applying the Laplace transforms with respect to time and the finite Fourier cosine transforms with respect to vertical co‐ordinates. This solution is used to produce the curves of dimensionless drawdown versus dimensionless time to investigate the influences of the patch zone and well partial penetration on the drawdown distributions. The results show that the dimensionless drawdown depends on the hydraulic properties of the patch and formation zones. The effect of a partially penetrating well on the drawdown with a negative patch zone is larger than that with a positive patch zone. For a single‐zone aquifer case, neglecting the effect of a well radius will give significant error in estimating dimensionless drawdown, especially when dimensionless distance is small. The dimensionless drawdown curves for cases with and without considering the well radius approach the Hantush equation (Advances in Hydroscience. Academic Press: New York, 1964) at large time and/or large distance away from a test well. Copyright © 2007 John Wiley & Sons, Ltd.     

Comparison of Kuqa foreland basin with Persian Gulf Basin in salt tectonics

Compared Kuqa foreland basin with Persian Gulf Basin in development of salt layers, salt tectonics, and the relation between salt tectonics and hydrocarbon, it is concluded that the salt diapirs are relative to hydrocarbon. Searching salt diapirs and related traps in Kuqa foreland basin is important. The forming mechanism of salt tectonic in Kuqa foreland basin is different from that of Hormuz Series, but similar to that of Lower Fars Series/Gachsaran Formation. Inspired by the role of salt tectonics of Lower Fars Series/Gachsaran Formation in hydrocarbon accumulation, the authors considered that the exploration below salt layer should be enforced, and the traps below salt layer in the southern part of the Kuqa foreland basin would be found where salt layer is thicker. On the contrary, the traps should be found both above and below the salt layer in front of the northern mountain where salt layer is thin. The Triassic and Jurassic source rocks are rich in this area with great exploration prospective.
