ЗАКОНОМЕРНОСТИ РАСПРЕДЕЛЕНИЯ СМЕЩЕНИЙ МАССИВА ГОРНЫХ ПОРОД В ЗОНЕ РАЗЛОМОВ С УСТАНОВИВШЕЙСЯ ПОЛЗУЧЕСТЬЮ Displacement distribution patterns and governing factors of rock mass in a stable creeping fault zone

Аннотация


Некоторые области разломов характеризуются установившимся квазистатическим движением со скоростью скольжения, сопоставимой с тектоническими скоростями от миллиметров до десятков миллиметров в год, вызывая деформацию массива горных пород в активных зонах. Авторами разработана механическая модель ползучести для разлома с учетом того, что характер перемещений зависит от статического смещения на разрыве, характеристик разлома и геологических условий. Распределение перемещений определяется по локальным напряжениям, механическим параме-
трам массива горных пород в зоне разлома, коэффициенту трения контактных поверхностей между ядром разлома и зоной повреждения и углу наклона разлома. Чем выше степень горизонтального выдавливания и чем мягче горная масса, тем выше степень концентрации смещения в ядре разлома.
