  在对重庆市的自然地理情况和社会经济情况作了介绍之后，还分析了重庆市水资源的基本特征，目前重庆市的水资源利用还处在传统的开发利用阶段，水资源管理体制还存在许多弊端，水的法规制度建设也相对落后，水的供给还不能完全满足需求，水质状况没有得到根本性的改善，水土流失还很严重，水旱灾害发生的频率比较高。针对重庆市水资源利用的现状，本文提出：应加强对水资源持续利用的认识；改革目前重庆市的水管理体制，尝试水务局管理体制，相应加强水的法规和制度建设，实现需水管理，建立节水型社会；根据实际情况，加强水利建设，实现水的供需平衡；依据“控源导流”的思想控制水污染，实现清洁生产；治理水土流失，保护水环境；建设防洪减灾体系。

  得到了以下结论： 1 )桩的相互作用因子随频率呈周期性变化，在振动频率比较低的情况下，桩的横向相互作用因子也较低，当频率趋近于零时，相互作用因子也趋近于零； 2 )桩的相互作用因子的幅值随瑞利波入射角度的变化而变化，在= 0情况下幅值最大，且随入射角度的增加，波动的周期明显缩短； 3 )桩的相互作用因子的幅值随着桩与桩间距的增加而减小，至s d = 15时，桩的相互作用因子基本趋近于0 ； 4 )在频率比较低时，相互作用因子幅值随桩土相对刚度比的增加而显著增加； 5 )桩顶固接可以有效地降低群桩的横向地震响应幅值，由瑞利波产生的群桩效应可以忽略不计； 6 )群桩中不同桩位的桩的横向地震响应是不同的，每根桩所在的桩位对其横向地震响应有很大的影响；刀桩数的增加并不能减小桩的横向动力响应。
