| 摘 要： | 工程冻害主要表现为;基土在冻融过程中.结构物或基础的各种冻胀及融沉破坏;江河水库等的冻结冰盖板对建筑物的静冰推力及动压力作用;工程材料的冻融损伤破坏。而冻害的实质是冻土(或冰)与结构物之间相互作用和相互适应的问题.本文从工程冻害防治的角度出发,分别对抗冻胀设计,冻害预测预报和防治措施优化等几方面,进行了初步分析与探讨.

| Abstract: | The phenomena of frozen damage to engineering could mainly be displayed as:Variouskinds of expanding/thawing damage which can occur when ground soil happen to be frozen /thawed;static thrust of ice and dynamic pressure against structure which could be producedby ice cover in the reserviors;frozen/thawimg damage to engineering materials The frozen damage is in essence a problem of interaction and adaptability between frozensoil/ice and structure.As viewed from preventing frozen damage to the engineering,the de-sign of resisting frozen expansion,forecast and optimization of cure measure for frozen dam-age,etc.are explored respectively in this paper. |
