北京浅山区建设场地岩土工程问题及对策
摘要:北京的城市建设已逐渐外扩至山区,浅山区较为复杂的自然地质状况和工程地质条件,对岩土工程勘察与评价提出了更高的要求,工程中面临的岩土工程问题也更多。本文结合实际工程,由浅山区的工程地质特点入手,从地形地貌、地层岩性及物质组成、不良地质作用以及工程地质条件等方面进行分析,总结出浅山区建设场地的岩土工程问题主要有斜坡稳定性问题、复杂地质条件下的不均匀地基以及特殊岩土等。设计时应根据具体的岩土工程条件,从避免形成高陡边坡,减小地基处理难度、降低造价等方面考虑优化设计方案,并重视地表排水措施及环境保护。针对不均匀地基的处理方法主要有结构措施、人工换填地基、复合地基、桩基础等。
Abstract:Beijing's urban construction has been gradually extended to mountain area. The complex nature geological conditions and engineering geological conditions of the shallow mountain put forward higher requirements of geotechnical engineering investigation and evaluation. In this paper, according to the actual engineering from the engineering geological characteristics of the shallow mountain, the topography, landfrom, formation lithology and lithology substance component, bad geology function and engineering geological conditions is analyzed The engineering geological problems of the shallow mountains are slope stability, uneven settlement under complicated geological conditions, and special soil. Design should be based on the geotechnical engineering condition, and avoiding the formation of high and steep slope, reducing the difficulty and cost of foundation treatment and other aspects optimization design, attention to surface drainage measures and environmental protection.According to the uneven ground treatment methods are mainly structural measures, artificial replacement foundation, composite foundation, pile foundation.
