摘　　要：为了探究黄土地区基坑降水工程对周边构筑物的损坏程度,基于突变系统模型理论,建立了黄土地区基坑降水对周边构筑物损坏因素分类标准和损坏评判突变模型,提出了基于突变级数理论的损坏评判方法,得到了基坑降水对周边构筑物损坏评判的分级标准.通过算例仿真和模型检验,结果表明:该突变级数损坏评判法实现了对周边构筑物损坏的有效评判.其操作性与实用性优于传统评判法.不依靠专家评判,显著降低了主观臆断性.该突变模型为基坑降水对周边构筑物影响分类评判提供了新途径.In order to explore the extent of damage of loess area dewatering project on the surrounding structures,Based on the theory of catastrophe system model, The establishment of the loess foundation pit dewatering on surrounding structures damage factors and damage evaluation model of mutation classification standard, A damage assessment method based on catastrophe progression theory is proposed. Classification criteria for the damage assessment of the surrounding structures in the foundation pit dewatering. By example simulation and model test, Results show that the catastrophe progression method is implemented to effectively judge the damage of surrounding structures. The operation and practicability is better than the traditional evaluation method, do not rely on expert judgment,significantly reduced the subjective. The catastrophe model provides a new way for the impact of the foundation pit precipitation on the surrounding structures.
