川藏公路沿線古冰磧區大型滑坡治理的
技術難題及對策
                   
摘要：根據近幾年川藏公路地質災害防治工作的科研成果和大量的實際經驗，總結高寒缺氧地區的特殊地層中，施工大孔徑高噸位預應力錨索工程，進行滑坡災害治理的技術難點及相應對策，并以川藏公路102滑坡群2號滑坡的整治工程予以說明。本文所介紹的內容對類似條件下的工程有借鑒用。

1、川藏公路沿線地質災害的主要形式及其危害程度
對地質學家而言，川藏公路素有地質博物館之美稱，沿線地形、地貌和地質現象的復雜性和多樣性其稱世界之最。
同樣，由于地形、地貌、地層條件及氣候的復雜性和多變性，使得川藏公路沿線的地質災害也表現出不同尋常的特殊性的復雜性。每年雨季，川藏公路沿線大大小小的滑坡、崩塌、泥石流、落石等地質災害頻頻發生，造成極為嚴重的經濟損失和社會影響，制約西藏地區的經濟發展，影響社會穩定。以著名的102滑坡群為例：該滑坡地區
Urban Land Development Traffic Impact Analysis and Models
Abstract: This paper summarizes a more comprehensive system of urban land development traffic impact analysis on the patterns and models, including traffic impact analysis of the general procedure, background traffic analysis, trip generation, trip distribution and traffic assignment, and the sensitivity analysis, service level main content. Although these models and models based on North American urban traffic characteristics and socio-economic value based on the idea, but not lose its general reference and guidance.

We know that land use is closely related with the traffic. The development of urban land value and development after the appeal to a large extent depends on the flow of traffic around the road system and good services. In general, reconstruction and extension through the road system, increase its capacity, can enhance the accessibility of urban land. However, this will stimulate a new land development activity, resulting in the new travel requirements. Will lead the new travel demand
