摘要
以500kV输电线路为例,施工塔基开挖涉及面积至少400m2以上。同时,在基坑开挖过程中将形成大量的施工弃渣。通过对大量威胁塔基安全的次生地质灾害进行统计分析,发现其发生的根本原因很多是因为施工弃渣不当造成,直接后果就是要么需进行岩土工程治理,要么进行改线,造成人力、物力的极大浪费,严重影响输电线路乃至电网的安全运行。因此,应高度重视塔基施工过程中的弃渣的处置问题。本文通过对大量因弃渣不当引起次生地质灾害问题的分析,研究弃渣对塔基稳定性影响的机理,总结其造成危害的类型,提出合理处置施工弃渣的措施,旨在防止输电线路建设过程中次生地质灾害的发生,有效维护电网的安全稳定运行。
Take the 500kV Transmission line as the example, the construction tower base excavates involves above area at least 400m^2.At the same time, will lbrm the massive constructions in the structure excavation process to abandon the dregs. Through carries on the statistical analysis to the massive threat tower base security secondary geology disaster, discovered it occurs the basic reason very are many is because constructs abandons the dregs not when creates, the direct consequence is either must carry on the ground project government, either canfes on re-routes, creates the manpower, the physical resource enormous waste, affects the transmission line and even the electrical network safe operation seriously. Therefore, should take in the tower base construction process highly the abandoned dregs handling question. Because this article through to massive abandons the dregs not when causes the secondary geology disaster question analysis, the research abandons the dregs to the tower base stability influence mechanism, summarizes it to cause the harm the type, proposed the reasonable handling construction abandons the dregs the measure, is for the purpose of preventing in the transmission line constTuction process the secondary geology disaster occurrence, maintains tbe electrical network effectively the security stable movement.
