中文摘要：

岩石的崩溃是土壤形成和地形学的主要过程之一并且更加走水路被影响并且加热。这研究在 Tuodian 镇上从侏罗记红床(J3t ) 的 Tuodian 组在典型紫色 mudstone 的实验室条件下面集中了于崩溃特征， Shuangbai 县，南部的中国的云南省。新鲜 mudstone 在五个处理期间受到水，热和热水的相互作用的轮流出现的应用：湿弄干(WD ) ，浸透(圣) ，加热制冷(RH ) ， wettingdrying 的联合并且加热制冷(WDRH ) ，并且浸透的联合并且加热制冷(STRH ) 。每个处理在 24 个周期被运用。结果证明有崩溃的三种类型：崩溃崩溃，脱落崩溃和细微崩溃。累积崩溃率(到创始的样品团的累积瓦解的质量的百分比通过了 2 公里筛) 当时，生产了 S 形状功能与处理周期时间有关并且仔细适合一个逻辑模型(R2 > 0.99 ) 。源于五个处理的累积崩溃率的等级顺序作为下列：WDRH > STRH > 圣 > WD > RH。因为潮湿和干的轮流出现的时期， WD 引起了大多数崩溃，当 RH 独自导致了细微崩溃时。另外，在每个处理周期(到对待的样品团的瓦解的质量的百分比) 和处理周期数字的崩溃率之间有否定关联。在潮湿的条件下面在这率和温度变化之间有积极关联，当水被供应时，显示在温度的一个变化极大地加速父母岩石的崩溃。

英文摘要：

Disintegration of rock is one of the primary processes of soil formation and geomorphology and is affected considerably by water and heat.This study focused on the disintegration characteristics under laboratory conditions of typical purple mudstone from the Tuodian group of Jurassic red beds（J3t） in Tuodian Town,Shuangbai county,Yunnan Province of southern China.The fresh mudstone was subjected to alternating applications of water,heat and hydrothermal interaction during five treatments：wetting-drying（WD）,saturation（ST）,refrigeration-heating（RH）,a combination of wetting-drying and refrigeration-heating（WDRH）,and a combination of saturation and refrigeration-heating（STRH）.Each treatment was run in twenty-four cycles.The results showed that there are three types of disintegration：collapsing disintegration,exfoliation disintegration and imperceptible disintegration.The cumulative disintegration rate（percentage of cumulative disintegrated mass to the initiative sample mass passed through a 2 mm sieve） produced a ＇S＇-shape function when related to treatment cycle time and closely fit a logistic model（R2 〉 0.99）.The rank order of the cumulative disintegration rate resulting from the five treatments was as the following：WDRH 〉 STRH 〉 ST 〉 WD 〉 RH.Because of alternating periods of moisture and dryness,WD caused the most disintegration,while RH alone resulted in imperceptible disintegration.Additionally,there was a negative correlation between the disintegration rate of each treatment cycle（percentage of disintegrated mass to the treated sample mass） and treatment cycle number.There was a positive correlation between this rate and temperature change under moist conditions,indicating that a change in temperature greatly accelerates the disintegration of parent rock when water was supplied.
