爱你的心超出了界限 我想拥有你所有一切 （伍佰 - 挪威的森林）
大考结束后，我跟班主任说，我不想也不能再继续念高中了，他沉默了几分钟，当
我正准备像在电视里看到的那样鞠躬说"谢谢老师一直以来的帮助"，他哑着嗓子开
口，
"我们一起去问问校长，你这样的情况，是不是有其他的办法。"
班主任领着我几乎是跑到校长办公室，一路上迈开大步走得飞快，我一路小跑跟着
他。到了校长面前，他铁青着脸，吓得校长以为我干了什么大逆不道的事。我朝他
看看，想暗示他快点说完就走吧，这样的气氛实在古怪尴尬。刚跨出校门没多久的
他，大约从没想过他光荣的教师生涯刚开始就会遇到这样在旧社会才会发生的倒霉
事，只说了一句，"程旭是个不错的同学"，便哽咽了。
我不敢再看他，怕看到他脸上还没褪去的青春痘红红地被泪水浸泡，实在有些滑稽
。头发花白的校长示意我先出去，我放轻脚步，退出校长办公室，站在透风的走廊
里有些局促不安，隐隐地听到办公室里传来的声浪，好像那些人讨论的是和我无关
的事，有种快睡着前身边有人说话的不真实感。我模糊地想着，这样的事，是给学
校和班级丢脸的吧，我为把这难题带给他们更甚于为自己难过。那时候的我们，年

谭家真是传奇啊，7代都在唱戏；
第一次听谭富英的戏是“草船借箭”，但主角是马连良，所以谭的光芒完全被盖住了，
后来听得多了，觉得还是赶不上余叔岩的唱。
但是谭家这个“舌侧音”的特点基本从谭富英开始就多少有了，到了元寿更甚；现在谭
正岩嗓子非常的亮，甚至有点“左”，其实可以学余，扬长避短，听小谭唱戏，一点都
不担心他的高腔，倒是觉得味道欠缺些。
有一版龙凤呈祥是小谭和薛亚萍唱的，太有喜剧效果了，老迈的刘备嗓子那么尖亮，青
春的尚香倒反而很深沉，虽然说是以老带新，可还是别扭。。。。

人言谭富英的唱法在解放后又是一变，尤其是向余叔岩琴师王瑞芝学习以后，韵味浓了
不少。我买的谭富英全集，听了后也是这个感觉。谭富英唱在细节上处理很多地方，要
比老谭余杨这一脉的简单，但由于嗓音条件优越，反而形成一种自然朴实酣畅淋漓的风
格，所以也很不容易。因为余没留下来这些戏的资料，但和杨宝森的比。谭富英后来录
的拿手戏，比如武家坡，定军山，战太平，二进宫，都不比杨的差，有些还略胜一筹。
但是学谭富英唱对嗓子要求很高，不仅要高亢又要宽广和响亮，一般的人有一条就不错
了。他的后人虽然唱的高，但是音窄，听得有些发尖就不太好听了。其实谭正岩的虽然
欠缺，但是比起他老爸谭曾效以前已经算是不错了。

quick and dirty check without using many soil properties: treat
the berm as rigid body, i.e., gravity retaining wall and check
against sliding and overturning.
But I strongly recommend doing a slope stability analysis considering
the soil properties below the berm.

Before you do any analysis:
1. Do you have soil boring data below the berm?
2. Do you have any lab testing data for the foundation soils and the
embankment fill?
The typical stability analysis in your case includes:
1. sliding
2. global stability analysis
3. seepage analysis
When you run global stability analysis:
1. What stress condition to use? Steady state or rapid drawdown?
2. What soil parameters to use? Effective stress soil parameters for steady
state, and total stress soil parameters for
