The Homestretch!
Now that you have readPart 1和Part 2在我们的斜坡稳定性系列中，您应该普遍了解“斜坡稳定性”是什么以及如何计划避免或响应斜坡故障。在我们系列的第三部分中，让我们走向岩石衰竭评估和减缓的岩土评估的元素。manbet万博app
Role of the Geotechnical Consultant
First, find a geotechnical consultant who can offer perspective in addition to services. How significant is the risk? What’s important to evaluate? What’s not? What are my options? Second, see that the scope of your geotechnical evaluation contains, at a minimum, provisions for a site reconnaissance, exploration and necessary instrumentation, material testing, engineering analyses, and qualification of your options for design and construction (with recommendations for implementation).
侦察
A reconnaissance is key to understanding risks and developing sound exploration and instrumentation, testing and analytical programs. Topography, vegetation, drainage, and evidence of failure help reveal something about failure drivers, mechanism and associated vulnerable materials.
Exploration and Instrumentation
Exploration is needed to allow the geotechnical consultant to understand and evaluate geometric, geologic and structural relationships in three-dimensions (breadth and width being visually determined, depth remaining the unknown), and select critical cross sections for analysis. If a slope failure has occurred or is suspected, boreholes are often instrumented with casings whose deflection over time can be measured to locate the depth and orientation of movement. Instrumentation is one item that can be overlooked or discounted due to the time required to detect movement or cost, but unless you measure it, how do you really know what the limits of movement are?
Material Testing
The geologic materials that comprise the site/slope must also be tested to determine their physical properties, including strength, which are needed to compute factors of safety against failure, determine allowable slope gradients, size structural reinforcing elements and more with confidence. Material testing is the most often discounted element of a geotechnical evaluation. Consider instead the impact of a thousand-dollar testing program when a slope repair, or the consequences of failure, are measured in the hundred thousand dollar range.
Engineering Analyses
展示岩土工程师对现场条件的解释需要分析，资格资格，技术方面的修复，并不仅为制定设计manbet万博app和建设（或重建）的建议，还提供了一种手段，而且还用于定价选项。有时工程师需要分析现有条件，也可以获得基线可以称重所提出的发展（或稳定）的影响。
Qualification, Design, and Construction
The results of the reconnaissance, exploration, instrumentation, testing and analytical programs are combined to qualify the options and develop a plan to move the site/project to safer ground. If your geotechnical consultant is experienced, they will be able to help you pursue a preferred option based on a balance of risk and cost, and also serve as a liaison to prospective earthwork and other specialty contractors. The geotechnical engineer will also need to observe and possibly prescribe tests during construction.
范围阶段
Finally, don’t assume you need to complete all these tasks in one lump sum. Until a reconnaissance is completed, the geotechnical engineer may not know where explorations or instruments should be located, whether there is access to them, and how much that effort will ultimately cost. Similarly, until the results of an instrumentation or material testing program are available, the engineer may not know how complicated a design or repair scheme may be. So, proceed smartly, incrementally – slope stability evaluations aren’t cheap, but your dollars can at least be targeted to obtain the best bang for the buck.
Conclusions
经验丰富的岩土工程师将评估岩石manbet万博app斜坡，天然和加固的土壤斜坡，悬臂和机械稳定的地球保留结构，开口和保留的挖掘，斜坡和墙壁故障，堤坝和坝体以及通道/海岸线结构。他们可以设计新的，以及评估现有（和失败）的结构。他们还协助编制和审查计划和规范，并提供纳入计划的部分和细节。
We are also involved in proactive hazard protection planning, working with municipalities to identify local geologic hazards such as historic failure types and limits, and severe foundation conditions, and have created feasibility maps for safely siting future flood protection structures. Such sites have then been revisited and analyzed more rigorously at the time plans for development are prepared.
