枣庄市是山东省岩溶地面塌陷的主要发育地区之一,岩溶地面塌陷灾害连年发生,给当地的生产、生活造成巨大经济损失,已成为该地区经济发展的制约因素。本文对该地区的地质条件、塌陷现状及岩溶地面塌陷的分布规律进行了分析归纳,从中得出枣庄岩溶地面塌陷容易发生在:在第四系厚度为5~10m的地段,时间为每年4~9月份,地势低洼处。本文从压力差的角度,在简要分析岩溶管道的发育程度、盖层条件的基础上,分析了地下水位在枣庄地面岩溶塌陷的控制作用,并以此为依据简要提出了几个防治建议。
Zaozhuang city is one of the major development karst collapse in Shandong Province,Where karst land collapse hazard occurs year after year,and it is harmful to the local production and living,hence it has become constraints to the region’s economic development.The geological conditions,the status quo of collapse and the distribution rules is studied in this paper,It is known that mostly karst collapse take place where quaternary thickness in 5 ~ 10m and where concentrated in from April to Sep every year and occurred mainly in low-lying places in zaozhuang.This paper from pressure difference angle to study on controling action of groundwater level of Zaozhuang karst collapse through analyze the degree of development of karst pore,cap rock conditions,the water table in the bedrock in the vicinity of the strong fluctuations and thus prevention and treatment recommendation sand is proposed.
