摘要

摘要: 为研究大型滑坡在发生时间呈现的规律,本文对我国近年来发生的大型滑坡在时间分布和诱导因素上进行了统计。从统计结果可以看出,自然边坡往往在一定的诱导因素下发生失稳破坏,而大型滑坡的失稳破坏在时间分布上则表现出望日或者朔日前后易于发生,并且滑坡在一天中发生的具体时刻则呈现出正态分布的特点。因此,根据固体潮的理论,以及固体潮在一天之中引潮力的变化与滑坡发生时刻的对应关系,本文认为固体潮是诱导大型边坡失稳的因素之一。同时由于组成边坡物质的蠕变特性不同,造成了大型滑坡的发生往往有超前或滞后现象,以上结果为滑坡的预报或预防工作提供了一定的理论支持。

Abstract: To study the phenomena of the large-scale landslides in the event of time occurrence,this paper conducts some statistics on the time of distribution and induction factors about the large-scale landslide,which occurred in recent years in China. Observed from the statistics about the time distribution and the induction factor of large-scale landslides,the natural slopes often had the destruction under certain induction factors.However,the large-scale landslide occurrence in the time distribution is easy to be found around plenilune or meniscus.The specific time which occurs in one day presents the characteristic of normal distribution.Therefore,according to the earth tide theory,as well as the time corresponding relations between the tide-producing force and the landslide occurrence during one day,this paper suggests the earth tide is one of the factors which induce instability of large scale landslide.Because simultaneously the creep characteristic of different materials which compose landslide is different,which caused the large-scale landslide occurrence often to have in advance or the hysteresis.The above result has provided certain theory support for the landslide forecast or prevention.
