| 中文摘要: |
| 基坑失稳风险评价对于基坑工程至关重要。首先研究失稳风险事件及其相关因素，建立风险分析模型和评判准则；然后考虑不同失稳形式的力学机理并基于可靠性理论确定基坑的风险概率；最后通过具体事例分析表明该方法的合理性和可行性。 |
| 英文摘要: |
| Risk assessment of foundation pit instability is very important for foundation pit engineering. First, it studies the instability risk events and their related factors, and establishes the risk analysis model and evaluation criteria. Then the mechanical mechanism of different instability forms is considered and the risk probability of foundation pit is determined based on the reliability theory. Finally, the rationality and feasibility of the method is analyzed by specific examples. |
