Chinese summary <53> 基于时序监测和数值模拟的地下储油库水幕参数研究

目的:地下水封石油洞库的水封性至关重要.水幕系统适用于地下水补给匮乏、稳定地下水位较低的地区,其性能取决于水幕参数的选择.不同参数(水幕孔间距、水幕孔与洞室高度差和水幕压力等)的水幕系统对洞室的水密性和稳定性有不同的影响.目前,地下油库的水幕系统设计还不够合理,亟需优化,但设计依据仍不足.本文希望通过对水幕系统参数的研究,为实际工程应用提供一些参考.
创新点:1. 通过现场渗压监测和气压监测,建立地下油库运营评价体系,及时了解运营状况;2. 通过有限元计算,对比不同水幕参数的优劣性,获得水幕参数的优化方案.
方法:1. 结合地质勘探资料,探讨水幕孔布孔方式的依据;2. 通过收集现场监测时间序列数据,采用时序分析法评价运营期间地下水封储油库的运营和水封效果,讨论可能出现的渗漏或过量涌水情况;3. 通过有限元仿真模拟,选择水幕系统的三个关键参数并进行优化,评价提出的水幕参数效益,提出适用于本项目的最优参数解.
结论:1. 黄岛地下水封石油洞库项目水幕系统最佳水幕孔间距为10 m,最合理的水幕孔与洞室高度差为25 m,最优水幕压力为70 kPa.2. 当水幕孔间距大于10 m时,水封效果提升不明显;考虑到经济成本(建设、运行和排水成本),这种改进是无效的.3. 当水幕孔与主洞的垂直距离为30~35 m时,水封失效;目前水幕系统的垂直影响范围约为25 m.4. 受地形因素的影响,主洞室周围的孔隙水压力存在显著差异;当水幕压力为60 kPa时,垂直水力梯度小于1.

Chinese summary <55> 一维应力状态下饱和黏土热应变响应本构研究

目的:基于热力耦合试验,揭示饱和黏土热塑性应变机理,提出一个更合理的热塑性方程,并用于描述复杂热力耦合条件下饱和黏土应变响应.
方法:1. 通过试验结果分析、理论推导提出本构关系;2. 通过参数分析和试验模拟,验证本构关系的有效性及合理性.
结论:通过对饱和黏土在不同热力耦合条件下的试验结果验证,本文提出的双屈服面热力耦合本构关系可以很好地模拟热循环下饱和黏土应变响应.

Chinese summary <58> 水盐效应对膨润土混合土力学特性的影响及评估方法研究

目的:揭示水盐效应对膨润土混合土的渗透系数和不排水剪切强度的影响.
创新点:1. 通过核磁及扫描电镜等手段从微观角度解释混合土力学指标的变化规律;2. 建立水盐效应下评估混合土的渗透系数和不排水剪切强度的经验关系式.
方法:1. 通过开展常规渗透试验和十字板剪切试验,揭示混合土力学指标的变化规律;2. 通过微观试验,分析影响力学指标的主要控制因素;3. 通过收集文献数据,验证经验关系式的可行性和有效性.
结论:1. 混合土的渗透系数随着膨润土含量的升高而降低;用盐水饱和的试样,其渗透系数偏大,而不排水剪切强度呈相反的趋势.2. 由核磁试验获得的试样孔隙分布可用来解释其渗透系数的变化规律.3. 文中提出的经验关系式能够较好地预测混合土的力学特性,包括渗透系数和不排水剪切强度.
