［摘要］在廣州市高技能人才實訓鑒定基地施工中，西側基坑支護結構出現(xiàn)了較大變形，曾一度出現(xiàn)了險情。采用對比分析法，對東西兩側基坑的受力及變形進行對比分析，找出西側基坑支護出現(xiàn)大變形的原因，即沒有對地面裂縫及時做灌漿填縫處理，雨水從地面縫隙和大樹根下逐漸長期滲入基坑西側土中所導致的；最后，介紹了應急搶險所采取的措施及搶險后筆者所得的啟示。
［關鍵詞］基坑支護； 大變形分析； 應急處理

Abstract:In the construction of Guangzhou High Skilled Personnel Training Appraisal Base, there was a large deformation in the retaining and protection on the west side of foundation pit and once created a dangerous situation. Using contrast analysis method, the force and deformation of the foundation pit unit on east and west sides of the object were compared and analyzed to find out the reasons for the large deformation of retaining and protection for the foundation pit on the west side. The cracks in the ground were not treated by grouting in time, so rain water gradually infiltrated into the soil on the west side of the foundation pit for a long time from the cracks in the ground and under the roots of the big trees. The emergency treatment measures of the retaining and protection structure, as well as the enlightenment after the emergency were also introduced.
Keywords:retaining and protection for foundation pit; large deformation analysis; emergency treatment
