In the paper, other research results are summarized, and a big test model indoor of row pile retaining and protecting deep foundation pit is designed. for homogeneous soil or samdwich soil structure three different retaining and protecting kinds : dense pile, thin pile and without pile are designed, using excavation simulation and loading on the top of slope, the model test is divided into two stages : foundation pit excavation simulation stage and destroy test stage. in this paper, for three different retaining and protecting kinds, the relation between soil pressure and displacement of piles, the relation between soil stress and strain, interaction of pile and soil and retaining and protecting loss - stability destroy are systemic studied
本文總結了前人研究成果，構築大型室內深基坑排樁支護試驗模型，在均質及層狀土層結構地基上，設計了密排樁、疏排樁及無支護三種不同支護型式，採用模擬開挖與坡頂均布加荷方式，進行了模擬基坑開挖和破壞性的兩個階段試驗，對三種不同支護型式的土壓力與樁位移、土體應力與變形、樁土共同作用及支護結構失穩破壞進行系統研究。 -
It showed the performance of anti - aging is good. the modified asphalt may be looked upon materials for highway road. the undee samdwich of the modified asphalt was characterized by sem
通過掃描電子顯微鏡（ sem ）分析表明改性后瀝青呈波浪形層狀結構，這一結構的形成同時改善了改性瀝青的高低溫性能。 -
The performance of high and low temperature was improved simultaneity because the materials of modified asphalt had structure of the undee samdwich. the modified asphalt was characterized by element analysis, tem, xrd, tg and ft - ir. we discussed the possible mechanism of the modification
另外，還採用了透射電子顯微鏡（ tem ） 、 x射線衍射（ xrd ） 、熱重摘要分析（ tg ） 、紅外光譜分析（ ft - ir ）等分析方法對改性瀝青進行了表徵，探討了可能的改性機理。 -
This paper chose the important part of environment field, namely temperature field as research object, looking pavement structure as samdwich, according to heat conduction theory deduce the analytic solution of one dimension unstable state temperature field modified by year temperature of pavement structure in natural environment, tested by practically measure, the analytic solution of temperature field accords with the temperature distributing law of pavement structure
道路環境場研究是路面長期性能研究的重要組成部分和基礎。本文選擇道路環境場中最主要組成部分? ?溫度場為研究對象，視路面結構為層狀體系，根據傳熱學原理推導出自然環境下經過年溫度修正的以天為周期的道路結構?維非穩態溫度場解析解，經過實測驗證，符合道路結構的溫度分佈規律。
