This second part of our three-part series on slope stability builds on our discussion of failure features, mechanics and triggering factors with guidelines for qualifying risk, identifying geotechnical needs, and responding to and preventing failures.

符合风险

OurPart 1discussion showed slope stability to be a complex topic, but also showed how much potential influence you can have over its prevention and, worst-case, mitigation. That influence is founded, however, on the understanding that:

1. 斜坡衰竭始终是一种可能性
2. 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。

不幸的是，可能没有任何可能因失败而导致失败的网站和项目最终因失败而受到影响，因为理解和升值是折扣或写入的（“我无法想象这里可能出错！”）。利益攸关方之间的不同经验和利益 - 市政当局，机构，土地所有者，开发商，顾问和其他影响因素 - 也风险偏离潜在风险（其中一些利益攸关方也可能不愿意面对这些风险）。虽然您无法控制别人如何接近问题，但您可以控制您如何接近它，以及他人如何回应它，以及一些岩土的视角。雷竞技的电竞比分网

Geotechnical Prerequisites

Any project on a site with vertical relief, or one involving grading that creates vertical relief (sloped or retained) is at risk to “slope” instability. When engaging such a project, you’ll want to gather information on:

• Geomorphic setting, including site and surrounding topography, geology, drainage, and historic site use.
• Project drivers, which offer much to think over, including: composition and quality of proposed foundation; cut, filled and retained materials; surface drainage and groundwater conditions; extent of cuts, fills, and structure loads; and stability and performance requirements (required factor of safety, allowable settlement, etc).
• 失效机制，包括深层和浅层故障，碎片流动或简单的侵蚀。

虽然您可能没有这种岩土内容的任何培训或经验，但这些词语本身应该引发一些直观的思想，这些因素将沉淀斜坡衰竭。雷竞技的电竞比分网最重要的是，请记住，您需要考虑并寻找的东西不限于您的项目或项目网站边界！

Failure Response

If, despite sound planning, design and construction, your site/project is impacted by a slope failure, you should have two plans – one for response and short-term triage, and a second for stabilization, repair or reconstruction. The hard and costly work of clearing debris, engaging consultants and contractors, and stabilizing or rebuilding a slope will always be waiting. In the meantime, however, safety should be your primary concern.

Hopefully the right help is only a call (or a few calls) away, but all responders should focus first on continued risks to the public. People should be kept well away and stay away from visible or suspected failure limits, and from structures impacted by the failure; there may be unstable earth masses or structures that have not failed but are at risk of failure. 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。

Moving forward, your investigation will contain a number of general tasks involving multiple parties:

• Problem discovery (what happened, what’s been impacted, who’s been impacted)
• 团队大楼（岩土工业，结构，公共雷竞技的电竞比分网机构，保险，合法）
• 替代追求（修复，重建，避免）
• Agency engagement (FEMA)
• Contracting (project management, insurance, legal)
• Construction (excavation contractor, specialty contractor, consultants)

From a geotechnical perspective, the investigation should also include the following discipline-specific tasks:

• Failure characterization (reconnaissance-based)
• 资源收集（根据需要钻取，采样，测试）
• 替代资格（分析和设计）
• 实施（建设）
• 施工监督（质量控制）

长期规划

展望前面的透视才能限制你发现自己倾向于倾向的次数。知识是预防的关键，并且知识可以在很多方面利用，包括：远离不稳定或潜在的不稳定区域（避免），设计和建设，以减轻已知或疑似失败风险（规划），以及建立或遵循控制如何接近失败风险风险的指南（规则）。有效的计划或监管要素包括危险评估，挫折分区，设计和施工指南和机构协调。设计前的小型投资，尤其建设可以在预防方面屈服于幅度的数量级。

Next Steps

Feeling educated but a bit bewildered? Don’t worry – our final installment on this topic will give you the low-down on what tools we can bring to bear on your next project, whether in anticipation of potential slope failure, or in response to a slope failure.
