根露出土
英文
heaving-
It divides the main vegetation of the headwater region of huangpu river into 4 categories based on field survey and observation and methods of factor analysis and systematic cluster analysis and according to the degree of soil and water conservation function : deciduous trees and shrubs are category 1 which shows very strong soil and water conservation function ; tea plantation, grasslands and pine trees are category 2 which has stronger function ; the category 3 is moso bamboos and broadleaved evergreen trees which have stronger permeability and erodibility, but the permeable performance is not outstanding, the capacity of soil moisture storage common and soil and water conservation function moderate and ; the category 4 is uncovered land where the soil and water conservation function is very weak and its permeability, erodibility, erosive resistance and soil moisture storage capacity are all notably smaller than that of the other lands
摘要在野外調查、實測的基礎上，採用因子分析、系統聚類分析的方法，根據土壤層水土保持功能的強弱，將黃浦江源區主要植被類型分為4類：落闊林、灌木林為第一類，表現出很強的水土保持功能；茶園、草地、松林為第二類，土壤水土保持功能較強；毛竹林、常綠闊葉林表現出較強的抗蝕性和抗沖性，但滲透性能並不突出，土壤貯水能力也一般，水土保持功能中等，為第三類；裸露地水土保持性能很差，單獨作為第四類，其滲透性、抗蝕性、抗沖性、土壤水庫容都顯著小於其他各樣地。Refer to the impacting - echo technology, we impacted the apex of the steel bar and incepted the reflecting stress ave through the resonator that fixed on the apex of the steel bar, and the value of the consolidating wave speed was calculated based on the time of stress wave transmitted and the length of the steel bar, so, identifying the reflecting signal is the key of the consolidating wave speed method
借鑒于沖擊回波技術，固結波速的測定方法是在鋼筋測桿的出露端施加瞬態沖擊載荷，由安設在測桿頂端的傳感器接收反射應力波信號，根據應力波的走時和測桿的長度折算固結波速的大小，因此反射信號的識別是固結波速法檢測混凝土強度的技術關鍵。According to author ' s practical experience accumulated in many years of water project construction, the author gives brief description to some common quality defects in cast - in - site concrete construction, such as honeycomb, ballast - surface, holes, reinforcement emerging, crack, surface unevenness, insufficient strength etc
根據在水利水電工程施工中多年積累的實踐經驗，簡要闡述了現澆混凝土施工中常見的一些質量缺陷，如混凝土出現蜂窩、麻面、孔洞、露筋、裂縫、表面不平整、強度偏低等。Someone think it must use permeating theory to design, the others think it must use permeating theory to design. the building ministry made out the working standard of the later pressure grouting of pour pile, but it stand at the industry standard, is n ' t enough perfect and comprehensive. in this paper, the author put forward the design principle by analyzing the reasons that affect the bear load ability of the drilling hole pour pile and the principle that improve the bear load ability of single pile by later pressure grouting, put forward th e working technology and requirement of check before acceptance by analyzing and summarizing several models such as the chinese railway 11 office residential high building
本文通過分析影響鉆孔灌注樁承載力的因素以及鉆孔灌注樁后壓漿提高單樁承載力的機理提出了設計計算的原則；通過中鐵十一局高層住宅樓鉆孔灌注樁低壓力后壓漿工程對6根樁的壓漿對比試驗及鉆探揭露確定了低壓力后壓漿所適用設計理論和方法；確定了低壓力后壓漿的壓漿壓力、壓漿量等參數；經過實驗及經驗總結確定了壓漿材料的選取原則及方法，列出了低壓力后壓漿在不同土層適用的壓漿材料。分享友人
