一、前言我国幅员广大,雨季时间长,每年都有大量水害发生。为了防止汛期路基边坡灾害的发生,工务现场必须:(1)合理安排防洪资金,提高其抗洪能力;(2)确定辖区范围内雨季度重点检查和监视的路基工点;(3)确定各个路基边坡的危险降雨量,做到及时派人检查监视。本文着重介绍日本近年来所采用和正在研究的“边坡安全度评分表”。这些表用评分的方法表示路基边坡的安全度,简易、快速、技术要求不高,一般工人都可掌握。
I. Preface Our country has a vast territory and a long rainy season, with a large number of water hazards occurring each year. In order to prevent the occurrence of side slope disaster in flood season, the work site must: (1) arrange flood control funds rationally and enhance their anti-flood capability; (2) determine the subgrade sites under the rainy season during the rainy season; (3) Dangerous subgrade slope rainfall, so as to send timely inspection and surveillance. This article focuses on the “Slope Security Rating Scale” adopted and under study in Japan in recent years. These tables use the method of grading to indicate the safety of the subgrade slope, which is simple, rapid and requires less technical requirements. The average worker can master it.
