Welcome Back!
我们的三部分系列的斜坡稳定性的第二部分建立了我们对失败特征，力学和触发因素的讨论，具有符合条件风险的准则，确定岩土性需求，并响应和防止失败。manbet万博app
Qualifying the Risk
我们的第1部分讨论表明，斜坡稳定性是复杂的话题，但也表明您可以在预防和最坏情况下减轻可能产生多少潜在影响。然而，这种影响成为了解：
- 斜坡衰竭始终是一种可能性
- 易感性和失败证据并不总是显而易见的，即使是受过训练的眼睛。
Unfortunately, sites and projects that may not otherwise be at risk to failure are ultimately impacted by failure because that understanding and appreciation are discounted or written off (“I can’t imagine what could go wrong here!”). Differing experiences and interests among stakeholders – municipalities, agencies, land owners, developers, consultants and other influencers – also risk deflecting attention away from potential risks (some of these stakeholders may also be reluctant to face those risks). While you can’t control how others approach the issue, you can control how you approach it, and how others respond to it, with some geotechnical perspective.
manbet万博app岩土技术先决条件
任何具有垂直浮雕的网站的项目，或涉及创造垂直浮雕（倾斜或保留）的分级的项目面临着“坡度”不稳定的风险。在参与这样的项目时，您将希望收集以下信息：
- 地貌设置，包括网站和周围地形，地质，排水和历史遗址使用。
- 项目司机提供了很多思考，包括：拟议基金会的组成和质量;切割，填充和保留材料;表面排水和地下水条件;切割，填充和结构负荷的程度;和稳定性和性能要求（安全，安全，允许的解决方案等）。
- Failure mechanisms, including deep-seated and shallow failures, debris flow or simple erosion.
While you may not have any training or experience with this geotechnical content, the words themselves should trigger some intuitive thoughts on the factors that combine to precipitate a slope failure. Most importantly, keep in mind that the things you need to consider and look for are not restricted to your project or project site boundaries!
失败响应
如果尽管进行了合理的规划，设计和施工，您的网站/项目受斜坡衰竭的影响，您应该有两个计划 - 一个用于响应和短期分类，一秒用于稳定，修理或重建。清除碎片，从事顾问和承包商以及稳定或重建斜坡的艰难和昂贵的工作将永远等待。然而，与此同时，安全应该是您的主要关注点。
希望正确的帮助只是一个电话（或几个电话），但所有的响应者都应该首先关注公众的持续风险。人们应该远离远离可见或疑似失败限制，并从破坏影响的结构;可能存在不稳定的地球群或结构，但没有失败，但面临失败的风险。In addition to a geotechnical engineer and/or geologist, you may need a structural engineer to examine buildings or walls, a city/county engineer or public works representative to examine impacted infrastructure, etc. There’s no harm in contacting local law enforcement to assist in site security and control, either.
当您占用的情况时，您将希望聘请顾问来履行初步评估，并制定调查计划以收集稳定或重建所需的信息。您还想聘请承包商协助清理，联系相关的救济机构，并确定是否需要公共或机构联络员将调查结果转化为调查和缓解活动的所有各方。
向前迈进，您的调查将包含许多涉及多方的一般任务：
- 问题发现（发生了什么，受到影响的是什么，受到了影响）
- Team building (geotechnical, structural, public agency, insurance, legal)
- Alternative pursuit (repair, rebuild, avoid)
- 代理商订婚（FEMA）
- 签约（项目管理，保险，合法）
- 建筑（挖掘承包商，专业承包商，顾问）
从岩土角度来看manbet万博app，调查还应包括以下特定的专用任务：
- 故障表征（侦察为基础）
- 资源收集(钻探、取样、测试needed)
- Alternative qualification (analysis and design)
- Implementation (construction)
- 施工监督（质量控制）
Long-Term Planning
Looking ahead with the proper perspective will hopefully limit the number of times you’ll find yourself dealing with a slope failure. Knowledge is key to prevention, and that knowledge can be leveraged in many ways, including: staying away from unstable or potentially unstable areas (avoidance), designing and building to mitigate known or suspected failure risks (planning), as well as establishing or following guidelines that control how sites at risk of failure are approached (regulation). Effective plan or regulatory elements include hazard assessments, setback zoning, design and construction guidelines, and agency coordination. Small investments in advance of design and especially construction could yield orders-of-magnitude savings in terms of prevention.
