题目内容
某砌体承重结构，底层砖墙370mm厚，采用钢筋混凝土条形基础。地质条件如下：地面下3.5m厚黏土层，物理性质指标：γ=18.6kN/m，ωL-=39．4%，ωp=23．2%，ω=26．6%，ds=2.70，Es=6.9MPa，fak=200kPa。其下为淤泥质土层，物理性质指标为：ω=52%，Es=2.3MPa，fak=76kPa。上部结构荷载效应为：正常使用极限状态下的荷载效应的标准组合：Fk=210kN/m，Mk=40kN·m承载能力极限状态下的荷载效应的基本组合：Fk=235kN/m，Mk=55kN·m试设计该基础(基础底面埋深可取2.0m，基础混凝土强度等级C20；100厚混凝土垫层C10；混凝土轴心抗拉设计强度ft=1.1N/mm2；钢筋采用HPB235，钢筋强度设计值：fy=210N/mm2)。 如果设计基础底宽度为b=1.5m，计算出基底附加压力为Po=120kPa，验算软弱下卧层的地基承载力特征值为（）。

某一饱和黏土地基，黏土层厚10m，渗透系数k=1.6cm/年，受大面积荷载Po=100kPa。 该黏土层的竖向固结系数，最接近的数值是（）。
Speech, whether oral or written, is a used commodity. If we are to be heard, we must (1) our words from those (2) to us within families, peer groups, societal institutions, and political networks. Our utterances position us both in an immediate social dialogue (3) our addressee and, simultaneously, in a larger ideological one (4) by history and society. We speak as an individual and also, as a student or teacher, a husband or wife, a person of a particular discipline, social class, religion, race, or other socially constructed (5) . Thus, to varying degrees, all speaking is a (6) of others’ words and all writing is rewriting. As language (7) , we experience individual agency by infusing our own intentions (8) other people’s words, and this can be very hard.(9) , schools, like into churches and courtrooms, are places (10) people speak words that are more important than they are. The words of a particular discipline, like those of "God the father" or of "the law," are being articulated by spokespeople for the given authority. The (11) of the addressed, the listener, is to acknowledge the words and their (12) . In Bakhtin’s (13) , "the authoritative word is located in a distanced zone, organically connected with a (14) that is felt to be hierarchally higher."(15) , part of growing up in an ideological sense is becoming more "selective" about the words we appropriate and, (16) , pass on to others. In Bakhtin’s (17) , responsible people do not treat (18) as givens, they treat them as utterances, spoken by particular people located in specific ways in the social landscape. Becoming alive to the socio-ideological complexity of language use is (19) to becoming a more responsive language user and, potentially, a more playful one too, able to use a (20) of social voices, of perspectives, in articulating one’s own ideas.
