简介:广西民族大学校长办公楼,绿意葱茏,花语鸟唱。三楼西北隅袁鼎生教授的办公室,风景尤好。窗外芳草新树,一池绿波,清风相逐,阳光明媚;室内人伴书香,诗散雅韵,文竹与野草相亲相长,一切都呈现出和谐整生的景象。袁教授在其间修养心性,处理公务,探索生态美学的奥秘,生发学术人生,可谓境与人谐。生于广西全州湘山湘水之间的袁教授,与大画家石涛同乡,集诗性、理性与哲性于一身。野趣横生、淘气调皮的童年生活,养成了他纯真天放的赤子心性和诗人情怀。早年在桂林广西师范大学工作期间,早登叠彩捧日出,夜赏漓江毛毛月,既能浅吟低唱出“天欲晓,最早醒来漓江鸟”的清明美好,也能挥毫出“端起天坑当酒杯”,“银河流觞唱兰亭”的气干霄云,还能飘逸出“一头老牛走来,侧听绿丝轻吐”的天态野趣。20世纪八九十年代,像郭靖转益多师一样,他吸纳诸位恩师的学术思想与学术方法,特别是导师周来祥先生的辩证方法,生发了生态辩证方法和整生范式。他潜心实践,将学术方法化成了超循环的概念运动理路。凡此种种,合塑了他的学术素质,成就了他的生态美学研究。袁教授是当代生态美学研究领域的大家之一。他的生态美学理论具有重要的开创意义,创立了一整套以审美场为核心的话语体系,以整生为基座的...
简介:摘要在现代化工程项目施工中,我们经常都会涉及到大体积混凝土施工问题。尤其是在土木工程施工中,其施工更为明显,但是在施工中由于土木工程与周围环境关系密切,因此在混凝土施工中极容易受到温度变化、湿度变化以及混凝土脆性不均匀的现象而造成混凝土施工裂缝。本文就土木工程施工中大体积混凝土的应用进行了分析,提出了混凝土裂缝的成因以及预防措施,以供同行工作参考。
