某岩石滑坡代表性剖面如下图所示。由于暴雨，使其后缘垂直张裂缝瞬间充满水，滑坡处于极限平衡状态（即滑坡稳定系数Ks＝1.0）。经测算，滑面长度L＝52m，张裂缝深度d＝12m，每延米滑体自重C=15000kN/m，滑面倾角θ=28°，滑面岩体的内摩擦角φ＝25°。则滑面岩体的黏聚力最接近（）。（假定滑动面未充水，水的重度可按10kN/m3计）
A．24kPa
B．28kPa
C．32kPa
D．36kPa
参考答案：C
解析：
①张裂缝的水压力

| When I was a teenager growing up in France, I wanted to leave school and have my own life. The only way I could do this was to work in the local paper factory in my town, or get married. I was very nervous then I told my 1 I wanted to leave school. I thought he would say, " 2 ! You are going to college." I was very 3 when he said, "OK. Let's go to the paper factory." Two days later, he took me to the factory. I imagined everyone to be friends 4 together and having fun. I even imagined there would be music and singing. I guess I had watched too many movies as a teenager. When we 5 the factory gate, my father spoke to the guard and one minute later we were 6 . I walked around the factory looking at the building, the workers, and listening to the noise. It was 7 . I ran back to my father and said, "I want to go home." He asked me,"What do you think of the factory?" "Too bad," I answered. "And marriage is even 8 !" he said. I went back to school the next day thinking about studying hard 9 I could get into a good college. I 10 studying English, so I decided to major in languages at college. Thanks to my father and our trip to the paper factory, I now work at the United Nations and my father is very proud of me. I married a very good man and my life is much better than it would have been working in the factory! | ||||
