Based on the results of exploration and in-site test of typical waste dump in southwest mountainous area,the analysis theory and method of waste dump rainfall infiltration are discussed beginning at analysing coal waste's mechanics characteristic and seepage theoty. Fllowed estimating method of waste dump stability is discussed influenced by rainfall. At last a typical engineering example of coal waste dump landslide influenced by rainfall is researched, acquiring research fruit hereinafter.①Particular exploration of typical waste dump in chongqing area and analysis estimate to its area engineering geology are done. Granule gradation、water content、nature density、dry densit etc parameter of waste granular media are tested. The mechanics characteristic of waste are researched by in-site shear experimentation、compressibility experimentation and infiltration experimentation.②The coal waste dumping is different from other consecutive solid material as incompact granule structure. Its shear strength and transforming characteristic also have itself characteristic.

本文针对山区矸石山，结合踏勘和现场试验，从分析矸石散体的力学特性以及渗流理论出发，研究了矸石山降雨入渗的分析理论与方法，在此基础上提出了矸石山体降雨作用下的稳定性评价方法，最后进行了降雨作用下典型矸石山滑坡工程实例研究，取得了以下研究成果：①对重庆山区中梁山、万盛、荣昌、天府、綦江等矿区代表性的矸石山进行详细踏勘，对矸石山的堆放形态及其区域的工程水文地质情况进行调查；针对重庆山区矸石山，测试矸石散体的颗粒级配、含水量、天然密度、干密度等参数、并在此基础上，通过现场剪切、压缩、渗透试验等研究矸石散体的力学特征。

Results show that the heavy rainfall event occurred under the favorable environmental conditions, resulted from the interaction of mid-and low-latitude systems. The mesoscale convergence and the mesoscale low triggered the occurrence of the heavy rainfall. Rain clusters bringing the heavy rainfall were related to meso-β systems. The meso-β mesoscale rain clusters appeared to the north of the cyclone center on 1000 hPa after filtering and to the south of the meso-α convergence line on 850 hPa.

分析表明：暴雨发生在高低空流场及中低纬系统配置非常有利的天气背景下，是多种尺度天气系统相互作用的结果；在对流性不稳定层结中，冷空气沿等熵面侵入到中尺度辐合系统中，激发了中尺度低涡的迅速发展，在孟加拉湾和南海源源不断输送的水汽配合下，导致了暴雨的发生；中β尺度对流雨团发生在滤波后1000 hPa 等压面的低涡中心北侧和850 hPa 中α尺度辐合线南侧，呈现暖式切变的降雨特征。

Based on cloud seeding data on April 5,2002 in Henan province,cloud seeding effects were evaluated by six methods,i.e.double contrast method of regional rainfall tendency control,regression analysis method of regional tendency correlation,multiple regression analysis method of regional tendency covariant,floating control historical regression method,cluster-analysis-based floating control historical regression method using rainfall as a covariant and CA-FCM using rainfall and atmospheric perceivable water as covariants.
