差异风化

在建立危岩的力学分析模型的基础上，研究了边坡中张性地应力和岩腔发育深度对差异风化型危岩形成与破坏的影响。

To study the influence of ground stress in rock slope and cave deepness to differential weathering overhanging rock , a mechanical model was proposed .

较小洞穴有裂隙状的渗流带洞穴、差异风化成因的壁龛式洞穴等。

While small caves belong to crack type percolating belt cave , and stable hole formed by different weathering functions .

陡崖或陡坡下岩性差异风化形成的岩腔是危岩崩落的起因。

Rock cells formed by the effects of different weathering of lithology of cliffs or steep slopes are the cause for collapse of perilous rock .

泥岩和砂岩、灰岩等软硬岩石之间的差异风化孕发了陡崖底部的岩腔，内部泥岩的应力风化加速了岩腔发育。

Different weathering velocities for sandstone , carbonite and mudstone triggered rock cells in mudstone below cliffs , weathering in stress status sped up the development of rock cells .

差异性风化岩石作为桩基持力层设计应注意的若干问题

Some Attentions to Design of Pile Load Bearing Stratum in Diversity Weathered Rock Stratum

基岩中存在软弱夹层为岩石的差异性风化的主要特征。

Soft layers in rock are the main features of weathered rocks of different degree .

随着软弱基座差异性风化的进一步发展、崖腔进一步扩大、卸荷裂隙逐渐连续贯通，危岩体将失去稳定产生崩塌。

The further development , the cliff cavity makes decent which along with the weak base difference further expands , the discharge crevasse continuously links up gradually , the danger crag body will lose stable and lead to avalanche .

认识风化程度的差异，给出各风化层的判别标准，这对于风化壳工程地质性状的研究，评价建筑场地的稳定性极为重要。

It is very important for engineering geological study and stability evaluation of constrution site and for analysis of different zones of the weathering crust .
