摘要:
针对膨胀土路堑边坡的公路工程特点,总结以往膨胀土路堑边坡的防护措施,根据以往膨胀土 路堑边坡的防护成败资料和经验,以保持边坡土体天然含水量状态的相对稳定,保持边坡土体结构的相 对完整性,保持边坡土体足够的抗剪强度和防护工程应能适应边坡膨胀土体可能产生的膨胀变形与膨 胀力不遭破坏。首先用DAH混合溶液改良膨胀土边坡的表层土,使DAH混合溶液与膨胀土产生离子 交换发生化学反应,从而使表层膨胀土体改变性能,成为正常土,然后结合以往路堑边坡处理方法进行 综合处理。实践证明,此方法不但充分利用了膨胀土,节约了工程投资,而且又绿化、美观了边坡,使其 与周围环境相协调,从而为膨胀土地区公路路堑边坡处理提供了一种切实可行的防护措施。
Abstract:
The cutting slope of expansive soil is the co nstruction formed by dig ging the soil when the hig hw ay g oes across expansive soil .It changes na tural condition, destroy s natural physiognomy , and demolishes natural balanceable conditions of rock stress .The cutting slope of expansive soil exposes soil to a cer tain embedding depth to atmosphere , w hich directly takes action with weathering agency like rainfall , evaporation and temperature , and changes environmental and hydro-geological co nditions within the slope soil . The paper , by countering the characteristic of highway engineering for the cutting slope to ex pansive soil, summarizes the past protective measures for cutting slope of expansive soil .In order to maintain the relative stability of natural moisture co ntent of slope soil, keep the relative integ rity of its structure , remain its enough shear strength and prevent swelling deformation and sw elling force of ex pansive soil from being destroyed, the paper put forw ard a new method of using DAH mix ed solution to improv e the surface soil of ex pansive soil slope according to the past information and ex perience of dealing with the cutting slope of expansive soil . The chemical reaction will bring about between DAH mix ed solution and the elements of ex pansive soil to produce ion exchange , so as to change the property of the surface expansive soil into normal soil.Besides , the paper makes full use of the past methods to cope w ith the cutting slo pe of ex pansive so that it can look for a better new method to deal with the cutting slope .In fact , the new method not only makes full use of expansive soil and economizes the engineering investment , but also affo rest the slope and cause it to coordinate with the sur roundings.In allusio n to the characteristic of the cutting slope of ex pansive soil, the paper tries to put forw ard an economy as well as reasonable project fo r dealing with the cutting slo pe of expansive soil, and provides reference basis for building highway in the area of expansive soil.
